description: The problem of the structure constants of the operator product expansions in the minimal models of conformal field theory is revisited. We rederive these previously known constants and present them in the form particularly useful in the Liouville gravity applications. Analytic relation between our expression and the structure constant in Liouville field theory is discussed. Finally we present in general form the three- and two-point correlation numbers on the sphere in the minimal Liouville gravity.

description: The development of novel materials for vacuum electron sources in particle accelerators is an active field of research that can greatly benefit from the results of \textit{ab initio} calculations for the characterization of the electronic structure of target systems. As state-of-the-art many-body perturbation theory calculations are too expensive for large-scale material screening, density functional theory offers the best compromise between accuracy and computational feasibility. The quality of the obtained results, however, crucially depends on the choice of the exchange-correlation potential, $v_{xc}$. To address this essential point, we systematically analyze the performance of three popular approximations of $v_{xc}$ (PBE, SCAN, and HSE06) on the structural and electronic properties of bulk Cs$_3$Sb and Cs$_2$Te, two representative materials of Cs-based semiconductors employed in photocathode applications. Among the adopted approximations, PBE shows expectedly the largest discrepancies from the target: the unit cell volume is overestimated compared to the experimental value, while the band gap is severely underestimated. On the other hand, both SCAN and HSE06 perform remarkably well in reproducing both structural and electronic properties. Spin-orbit coupling, which mainly impacts the valence region of both materials inducing a band splitting and, consequently, a band-gap reduction of the order of 0.2 eV, is equally captured by all functionals. Our results indicate SCAN as the best trade-off between accuracy and computational costs, outperforming the considerably more expensive HSE06.

description: A high-strength concrete and mortar subjected to compressive fatigue loading were compar-atively investigated using experimental and computational techniques. The focus of the investigations was on the influence of the coarse aggregate in high-strength concrete. Accordingly, the fatigue behaviour was analysed experimentally using the macroscopic damage indicators strain, stiffness and acoustic emission hits. The results clearly show differences in the fatigue behaviour between the concrete and the mortar, especially at the lower stress level investigated. The basalt coarse aggregate here improves the fatigue behaviour of the concrete. Indication of a negative effect can be seen at the higher stress level. A finite element approach with a gradient-enhanced equivalent strain-based damage model combined with a fatigue model was used for the computational simulation of the fatigue behaviour. The damage model includes a differentiation between tension and compression. The fatigue model follows the assumption of the reduction in the material strength based on the accu-mulated gradient-enhanced equivalent strains. A random distribution of spherically shaped basalt aggregates following a given particle size distribution curve is used for the simulation of concrete. The comparison of the experimentally and computationally determined strain developments of the concrete and mortar shows very good agreement.

description: Yebes 40\,m radio telescope is the main and largest observing instrument at Yebes Observatory and it is devoted to Very Long Baseline Interferometry (VLBI) and single dish observations since 2010. It has been covering frequency bands between 2\,GHz and 90\,GHz in discontinuous and narrow windows in most of the cases, to match the current needs of the European VLBI Network (EVN) and the Global Millimeter VLBI Array (GMVA). Nanocosmos project, a European Union funded synergy grant, opened the possibility to increase the instantaneous frequency coverage to observe many molecular transitions with single tunnings in single dish mode. This reduces the observing time and maximises the output from the telescope. We present the technical specifications of the recently installed 31.5-50 GHz (Q band) and 72-90.5 GHz (W band) receivers along with the main characteristics of the telescope at these frequency ranges. We have observed IRC+10216, CRL 2688 and CRL 618, which harbour a rich molecular chemistry, to demonstrate the capabilities of the new instrumentation for spectral observations in single dish mode. The results show the high sensitivity of the telescope in the Q band. The spectrum of IRC+10126 offers a signal to noise ratio never seen before for this source in this band. On the other hand, the spectrum normalised by the continuum flux towards CRL\,618 in the W band demonstrates that the 40~m radio telescope produces comparable results to those from the IRAM 30~m radio telescope, although with a smaller sensitivity. The new receivers fulfil one of the main goals of Nanocosmos and open the possibility to study the spectrum of different astrophysical media with unprecedented sensitivity.

Research funding randomly allocated? A survey of scientists' views on peer review and lottery

description: The bold idea of random grant allocation is heatedly discussed as an alternative to peer review. The debate centers on advantages and disadvantages of the established measures to control scientific quality, compared to funding by chance. Recently, studies also investigated acceptance of lotteries in the scientific field. However, they provide only inconclusive findings due to their restricted scope. This paper examines scientists' views on current funding conditions and the idea of random grant distribution. An online survey of PhD holders reveals that most participants are against pure randomness, although they would try random elements if such procedures were combined with peer review. Moreover, while fewer established and recognized scientists differ in their assessments of peer review and expectancies on lotteries' impact, they hardly vary in their positions on random elements. Funding organizations therefore should be encouraged to further experiment with, and closely examine, practiced lotteries.

description: A fully relativistic modified gravitational theory including a fifth force skew symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distance scales of the gravitational constant G, the fifth force skew symmetric field coupling strength omega and the mass of the skew symmetric field mu=1/lambda. A fit to the available anomalous acceleration data for the Pioneer 10/11 spacecraft is obtained for a phenomenological representation of the "running" constants and values of the associated parameters are shown to exist that are consistent with fifth force experimental bounds. The fit to the acceleration data is consistent with all current satellite, laser ranging and observations for the inner planets.

description: Objectives: The coronavirus disease 2019 (COVID-19) has caused a crisis worldwide. Amounts of efforts have been made to prevent and control COVID-19′s transmission, from early screenings to vaccinations and treatments. Recently, due to the spring up of many automatic disease recognition applications based on machine listening techniques, it would be fast and cheap to detect COVID-19 from recordings of cough, a key symptom of COVID-19. To date, knowledge of the acoustic characteristics of COVID-19 cough sounds is limited but would be essential for structuring effective and robust machine learning models. The present study aims to explore acoustic features for distinguishing COVID-19 positive individuals from COVID-19 negative ones based on their cough sounds. Methods: By applying conventional inferential statistics, we analyze the acoustic correlates of COVID-19 cough sounds based on the COMPARE feature set, i.e., a standardized set of 6,373 acoustic higher-level features. Furthermore, we train automatic COVID-19 detection models with machine learning methods and explore the latent features by evaluating the contribution of all features to the COVID-19 status predictions. Results: The experimental results demonstrate that a set of acoustic parameters of cough sounds, e.g., statistical functionals of the root mean square energy and Mel-frequency cepstral coefficients, bear essential acoustic information in terms of effect sizes for the differentiation between COVID-19 positive and COVID-19 negative cough samples. Our general automatic COVID-19 detection model performs significantly above chance level, i.e., at an unweighted average recall (UAR) of 0.632, on a data set consisting of 1,411 cough samples (COVID-19 positive/negative: 210/1,201). Conclusions: Based on the acoustic correlates analysis on the COMPARE feature set and the feature analysis in the effective COVID-19 detection approach, we find that several acoustic features that show higher effects in conventional group difference testing are also higher weighted in the machine learning models.

description: In many instances of online collaboration, ideation and deliberation about what to write happen separately from the synthesis of the deliberation into a cohesive document. However, this may result in a final document that has little connection to the discussion that came before. In this work, we present interleaved discussion and summarization, a process where discussion and summarization are woven together in a single space, and collaborators can switch back and forth between discussing ideas and summarizing discussion until it results in a final document that incorporates and references all discussion points. We implement this process into a tool called Wikum+ that allows groups working together on a project to create living summaries-artifacts that can grow as new collaborators, ideas, and feedback arise and shrink as collaborators come to consensus. We conducted studies where groups of six people each collaboratively wrote a proposal using Wikum+ and a proposal using a messaging platform along with Google Docs. We found that Wikum+'s integration of discussion and summarization helped users be more organized, allowing for light-weight coordination and iterative improvements throughout the collaboration process. A second study demonstrated that in larger groups, Wikum+ is more inclusive of all participants and more comprehensive in the final document compared to traditional tools.

We give predictions for both the differential cross section $dσ/dm$ and the spin density matrix elements of the virtual photon that decays into the lepton pair. In the studied energy range, the cross section is dominated by the Born and $N(1520)$ contributions.

description: We point out that Kaluza-Klein (KK) dark matter physics is drastically affected by second KK particles. In this work various interesting phenomena caused by the second KK modes are discussed. In particular, we reevaluate the annihilation cross section and thermal relic density of the KK dark matter quantitatively in universal extra dimensions, in which all the standard model particles propagate. In these models, the first KK mode of $B$ boson is a viable dark matter candidate by virtue of KK-parity. We demonstrate that the KK dark matter annihilation cross section can be enhanced, compared with the tree level cross section mediated only by first KK particles. The dark matter mass consistent with the WMAP observation is increased.

description: In studying the dynamics of large N_c, SU(N_c) gauge theory at finite temperature with fundamental quark flavours in the quenched approximation, we observe a first order phase transition. A quark condensate forms at finite quark mass, and the value of the condensate varies smoothly with the quark mass for generic regions in parameter space. At a particular value of the quark mass, there is a finite discontinuity in the condensate's vacuum expectation value, corresponding to a first order phase transition. We study the gauge theory via its string dual formulation using the AdS/CFT conjecture, the string dual being the near-horizon geometry of N_c D3-branes at finite temperature, AdS_5--Schwarzschild X S^5, probed by a D7-brane. The D7-brane has topology R^4 X S^3 X S^1 and allowed solutions correspond to either the S^3 or the S^1 shrinking away in the interior of the geometry. The phase transition represents a jump between branches of solutions having these two distinct D-brane topologies. The transition also appears in the meson spectrum.

description: Despite the growing interest for autonomous environmental monitoring, effective SLAM realization in native habitats remains largely unsolved. In this paper, we fill this gap by presenting a novel online graph-based SLAM system for 2D LiDAR sensor in natural environments. By taking advantage of robust weighting scheme, sliding-windowed optimization, fast scan-matcher and parallel computing, our system not only delivers stable performance in cluttered surroudings but also meets real-time constraint. Simulated and experimental results confirm the feasibility and efficiency in the overall design of the proposed system.

Experimental efforts have followed and significantly reduced those uncertainties. This is important for the evaluation of nova contribution to galactic chemical evolution, gamma--ray astronomy and possibly presolar grain studies. In particular, estimations of expected gamma-ray fluxes are essential for the planning of observations with existing or future satellites.

Mathematics anxiety and the first year university introductory Calculus course
Creators: name: Stevens, Pierre
Publisher: name: University of British Columbia
Year: 2009

description: Mathematics departments experience large dropout rates among first-year students. Attempts have been made to remedy this attrition by focusing on curriculum reform and teaching-learning techniques. Less effort has gone into exploring the differences in values, beliefs, expectations and experiences of teachers and students in a first year calculus course. The purpose of this study was to identify these differences in an effort to determine the circumstances under which teaching and learning takes place in the classroom. Identification of possible mismatches may provide a beneficial insight towards improving the pedagogy of mathematics education in the first year calculus classroom. To that extent, I conducted open-ended interviews and questionnaires with five faculty members and with five students. The research was carried out at the mathematics department of a Research University in Eastern Canada. Interpretative analysis of the data focused on three spheres of interest: beliefs about: the nature of mathematics, the pedagogy of mathematics education, and the aims of mathematics education and post-secondary university education. It was found that differing perspectives for the first two spheres contribute to mathematics anxiety among first year students. To address mathematics anxiety within the first-year introductory calculus course, the study suggests that there is a need to (I) develop a social constructivist theory of mathematics anxiety, (2) develop within the professional practice of post-secondary mathematics education an awareness of the role of communication, and (3) develop within post-secondary educational institutions an awareness of the benefit of nurturing research among instructors into their individual teaching practices.

description: We investigate the behavior of a threshold model for the spreading of fads and similar phenomena in society. The model is giving the fad dynamics and is intended to be confined to an underlying network structure. We investigate the whole parameter space of the fad dynamics on three types of network models. The dynamics we discover is rich and highly dependent on the underlying network structure. For some range of the parameter space, for all types of substrate networks, there are a great variety of sizes and life-lengths of the fads -- what one see in real-world social and economical systems.
Chaos in the Bose-glass phase of a one-dimensional disordered Bose fluid

description: We show that the Bose-glass phase of a one-dimensional disordered Bose fluid exhibits a chaotic behavior, i.e., an extreme sensitivity to external parameters. Using bosonization, the replica formalism and the nonperturbative functional renormalization group, we find that the ground state is unstable to any modification of the disorder configuration ("disorder" chaos) or variation of the Luttinger parameter ("quantum" chaos, analog to the "temperature" chaos in classical disordered systems). This result is obtained by considering two copies of the system, with slightly different disorder configurations or Luttinger parameters, and showing that inter-copy statistical correlations are suppressed at length scales larger than an overlap length $ξ_{\mathrm{ov}}\sim |ε|^{-1/α}$ ($|ε|\ll 1$ is a measure of the difference between the disorder distributions or Luttinger parameters of the two copies). The chaos exponent $α$ can be obtained by computing $ξ_{\mathrm{ov}}$ or by studying the instability of the Bose-glass fixed point for the two-copy system when $ε\neq 0$. The renormalized, functional, inter-copy disorder correlator departs from its fixed-point value -- characterized by cuspy singularities -- via a chaos boundary layer, in the same way as it approaches the Bose-glass fixed point when $ε=0$ through a quantum boundary layer. Performing a linear analysis of perturbations about the Bose-glass fixed point, we find $α=1$.

description: Just as the Hamming weight spectrum of a linear block code sheds light on the performance of a maximum likelihood decoder, the pseudo-weight spectrum provides insight into the performance of a linear programming decoder. Using properties of polyhedral cones, we find the pseudo-weight spectrum of some short codes. We also present two general lower bounds on the minimum pseudo-weight. The first bound is based on the column weight of the parity-check matrix. The second bound is computed by solving an optimization problem. In some cases, this bound is more tractable to compute than previously known bounds and thus can be applied to longer codes.

A study of extreme water waves using a hierarchy of models based on potential flow theory
Creators: name: Choi, Junho
Publisher: name: Zenodo
Year: 2024

description: # User instructions

Program that solves the Potential Flow Equations (PFE) on a 3D periodic domain using the modified mid-point scheme.

The simulation tracks the evolution of three line solitons as they interact, to produce an eight times higher splash than the initial height of each soliton.

## FILES

The code consists of five files:- `pot_sp3.py` is the main file that solves PFE;- `PFE_sp3energy.py`, `PFE_sp3_max.py`, `PFE_sp3_A.py`, and `PFE_sp3_maxA.py` are used for plotting the evolution of energy and maximum, amplitude of solitons in a far field (denoted by A), and maximum divided by A, respectively.

After the computation of `pot_sp3.py` is finished, four sets of data are produced:- solutions eta and Phi in "*data/height.pvd*", "*data/psi.pvd*", "*data/varphi.pvd*";- evolution of energy and maximum against time is saved in "*data/potflow3dperenergy.txt";

The computational data can be visualised as follows:- Solutions eta and Phi are pvd files that can be read with Paraview, which reproduce Fig.11 in referene [1].- Time evolution of energy can be plotted by running file `PFE_sp3_energy.py`, which reproduces Fig.13(d) in [1].- Time evolution of maximum of eta can be plotted by running file `PFE_sp3_max.py`, which reproduces Fig.13(a) in [1].- Time evolution of A can be plotted by running file `PFE_sp3_A.py`, which reproduces Fig.13(b) in [1].- Time evolution of maximum/A can be plotted by running file `PFE_sp3_maxA.py`, which reproduces Fig.13(c) in [1].

We provide a table in which parameters were uses for setting simulations as follows. We denote spatial resolution by $\Delta x\approx\Delta y=200$. $T$ is the total simulation time defined as $T=t_{end}-t_{0}$ with $t_0=0{\rm s}$. $\Delta t=0.7139{\rm s}$ or $\Delta t BLE=0.005$.  In order to change order of basis, modify nCG (currently setting nCG=2). For $N_y$, modify multiple (currently setting mutiple=3), for $\Delta t BLE$ modify dtBLE(currently setting dtBLE=1/200).  All simuations were run on 40 cores of Leeds' arc4-HPC. The table below appears within the caption of fig.13 in [1].

description: The characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved. In this review, we first summarize the cutting-edge states of the exoplanet and disk observations. We further present a comprehensive panoptic view of modern core accretion planet formation scenarios, including dust growth and radial drift, planetesimal formation by the streaming instability, core growth by planetesimal accretion and pebble accretion. We discuss the key concepts and physical processes in each growth stage and elaborate on the connections between theoretical studies and observational revelations. Finally, we point out the critical questions and future directions of planet formation studies.

description: Esta dissertação investiga a produção de jogos digitais paródicos realizados pela desenvolvedora CyberGamba e suas relações possíveis com a carnavalização e o movimento antropofágico. A produtora paulista criou uma série de jogos digitais se apropriando do universo do programa televisivo Chaves entrelaçado a outras obras desenvolvidas pela indústria de jogos digitais. A pesquisa presente é estruturada da seguinte maneira: inicialmente, são abordados, teoricamente, os jogos digitais e as suas dinâmicas de criação e modificação; a seção seguinte é dedicada aos conceitos de carnavalização, aproximando-os à antropofagia e contextualizando a produção de CyberGamba. Por último, analisa-se a produção da desenvolvedora e investiga-se a polifonia estabelecida entre as obras examinadas. A estratégia metodológica de um estudo de caso em jogos digitais seguiu em consonância com os trabalhos de Robert Yin e Espen Aarseth, colaborando com o plano abordado na presente pesquisa e contribuindo para as análises não lineares das obras levantadas. Por fim, as produções paulistas mostraram-se objetos de pesquisa carnavalizados, estruturando novos diálogos, clarificando potências e desvelando problematizações e tensões oriundas da polifonia realizada. This dissertation investigates the production of parodic digital games made by the developer CyberGamba and its possible relationships with carnivalization and the anthropophagic movement. The producer from São Paulo created a series of digital games, appropriating the universe of the television program Chaves intertwined with other works developed by the digital games industry. The present research is structured as follows: initially, digital games and their dynamics of creation and modification are theoretically addressed; the next section is dedicated to the concepts of carnivalization, bringing them closer to anthropophagy and contextualizing the production of CyberGamba. Finally, the developer's production is analyzed and the polyphony established among the works examined is investigated. The methodological strategy of a case study in digital games followed in line with the works of Robert Yin and Espen Aarseth, collaborating with the plan addressed in this research and contributing to the non-linear analysis of the works raised. Finally, the productions from São Paulo proved to be objects of carnival research, structuring new dialogues, clarifying powers and unveiling problems and tensions arising from the polyphony carried out.

description: We construct and investigate quantum fields induced on a d-dimensional dissipationless defect by bulk fields propagating in a (d+1)-dimensional space. All interactions are localized on the defect. We derive a unitary non-canonical quantum field theory on the defect, which is analyzed both in the continuum and on the lattice. The universal critical behavior of the underlying system is determined. It turns out that the O(N)-symmetric phi^4 theory, induced on the defect by massless bulk fields, belongs to the universality class of particular d-dimensional spin models with long-range interactions. On the other hand, in the presence of bulk mass the critical behavior crossovers to the one of d-dimensional spin models with short-range interactions.

description: It is well-known that the original lattice Boltzmann (LB) equation deviates from the Navier-Stokes equations due to an unphysical velocity dependent viscosity. This unphysical dependency violates the Galilean invariance and limits the validation domain of the LB method to near incompressible flows. As previously shown, recovery of correct transport phenomena in kinetic equations depends on the higher hydrodynamic moments. In this Letter, we give specific criteria for recovery of various transport coefficients. The Galilean invariance of a general class of LB models is demonstrated via numerical experiments.
Microcavity resonance condition, quality factor, and mode volume are determined by different penetration depths

description: The penetration depth in a Distributed Bragg Reflector (DBR) co-determines the resonance condition, quality factor, and mode volume of DBR-based microcavities. Recent studies have used an incomplete description of the penetration depth and incorrect equations. We present a complete analysis that involves three different penetration depths. We also present a series of experiments on microcavities to accurately determine the frequency and modal penetration depth of our DBRs and compare these results with theoretical predictions. The obtained results are relevant for anyone who models a DBR as an effective hard mirror if lengths of the order of the wavelength are relevant, as is the case for microcavities.

description: This research is intended to help meet the growing demand for green schools that foster sustainability education by aggregating and cross-analyzing specific pedagogical strategies from buildings currently being used as teaching tools for sustainability. Over 350 specific teaching strategies were collected from 15 of the world’s highest performing academic buildings using Anne Taylor’s theoretical framework for linking architecture with sustainability education. These strategies were collected through interviews, literature reviews, web content, course curriculums, photographs, and site visits. This research also analyzed current educational theory that can be extended to the physical built environment, which was used to qualitatively analyze each pedagogical strategy. To specifically focus the data collection process, 36 of the most important sustainability issues related to the built environment were also compiled for this research and used to organize the teaching strategies. Additionally, four thematic categories (Multisensory, Outreach, Curricular, and Research) were created to organize the strategies based on their different educational goal, method of knowledge transfer, and intended audience. Finally, the 368 teaching strategies were cross-analyzed to determine the most common overall pedagogical strategies currently used. Educators, designers, and facility planners should use the information presented in this paper as a foundation for innovation in educational planning and design innovation. Also, the most common teaching strategies should be considered a benchmark for future buildings that teach. This list is not exhaustive, however, as the potential strategies for utilizing a building as a teaching tool is likely limitless. Therefore, all of the collected teaching strategies (over 350, attached in the Adobe Portfolio) are presented as individual design cards to display the pedagogical possibilities of buildings that teach and to inspire innovating strategies in the future.

description: “At the same time that we must respond to climate change and rising energy costs, we must also adjust our housing stock to fit a changing demographic and find more frugal form of prosperity. Such a transformation will require deep change, not just in energy sources, technology, and conservation measures but also in urban design, culture and lifestyles. More than just deploying green technologies and adjusting our thermostats, it will involve rethinking the way we live and the underlying form of our communities.” (Calthorpe, 2011) Our cities are built dependent on centralized systems of water and waste management, food and energy production. This practice has proven efficient for a while; nonetheless as our cities expand with immense speed and population increases, severe issues of food access, waste accumulation, floods, water contamination and increased energy demand reveal the obsolescence of those systems. The solution does not lie anymore only in conservation and precautionary measures but in a diverse way of thinking and redesigning existing infrastructures. Through this thesis, several systems of urban agriculture, decentralized water management and treatment, as well as energy production from waste were identified and studied through literature and actual case studies. The ultimate goal of the research was to create a toolkit for urban regenerative environments, which will be used to introduce those systems to designers. The key component of the toolkit is the quantitative link between the spatial demands of each system and its efficiency.

Troubling the taken-for-granted : mentoring relationships among women teachers
Creators: name: Thompson, Merrilee Susan
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation challenges the traditional patriarchal conception of mentoring, in which mentors are cast as experts and the task for novices is to assimilate their mentors' knowledge and proposes an alternate feminist conception in which mentors and novices are learner-teachers. The conception is based on practices of conversation and shared experience, through which mentoring partners develop trust and reciprocity. Through reciprocity, mentoring dyads move to a practice of thoughtful critique, in which they trouble taken-for-granted structures within schools. Central to feminist mentoring are issues of concern to the teachers involved, including issues of gender, race and culture as experienced in their own lives. To explore the conception of feminist mentoring, a qualitative research study was undertaken. Data about four mentoring dyads and one triad were collected through a series of structured interviews with individuals and pairs of teachers during one school year. The interviews were recorded and transcribed, and the resulting transcripts were analyzed for common themes. It was found that more successful dyads formed on the basis of the beginning teacher's choice and involved considerable time commitment. Successful mentoring dyads participated in frequent conversations, both casual and planned, in which they talked about students, shared resources, and co-planned curriculum. Conversations centred on both work-related and personal issues. The most successful dyad created numerous shared experiences which provided opportunities for the partners to learn reciprocally. Mentoring conversations and shared experiences led to two complementary ways of coming to know about teaching. In percolated learning the beginning teacher came to know based on hearing and thinking about the mentor's experiences. Thoughtful critique is a more deliberate mode of learning in which the mentor and beginning teachers intentionally address issues of common concern. Although there was some evidence of explicit thoughtful critique emerging within the mentorships, critique was expressed tentatively and cautiously. I suggest that the conditions of schools discourage critique and beginning teachers feel discouraged from being overtly critical. Mentoring dyads may need to work together for more than one year to develop a sufficient level of trust to move to a more critical feminist reconception of mentoring that supports and challenges both mentors and beginning teachers.
Production of black holes and their angular momentum distribution in models with split fermions

description: In models with TeV-scale gravity it is expected that mini black holes will be produced in near-future accelerators. On the other hand, TeV-scale gravity is plagued with many problems like fast proton decay, unacceptably large neutron-antineutron oscillations, flavor changing neutral currents, large mixing between leptons, etc. Most of these problems can be solved if different fermions are localized at different points in the extra dimensions. We study the cross-section for the production of black holes and their angular momentum distribution in these models with "split" fermions. We find that, for a fixed value of the fundamental mass scale, the total production cross section is reduced compared with models where all the fermions are localized at the same point in the extra dimensions. Fermion splitting also implies that the bulk component of the black hole angular momentum must be taken into account in studies of the black hole decay via Hawking radiation.

description: We investigate asymptotic symmetries in flat backgrounds of dimension higher than or equal to four. For spin two we provide the counterpart of the extended BMS transformations found by Campiglia and Laddha in four-dimensional Minkowski space. We then identify higher-spin supertranslations and generalised superrotations in any dimension. These symmetries are in one-to-one correspondence with spin-$s$ partially-massless representations on the celestial sphere, with supertranslations corresponding in particular to the representations with maximal depth. We discuss the definition of the corresponding asymptotic charges and we exploit the supertranslational ones in order to prove the link with Weinberg's soft theorem in even dimensions.
