Search for new non-resonant phenomena in high-mass dilepton final states with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for new physics with non-resonant signals in dielectron and dimuon final states in the mass range above 2 TeV is presented. This is the first search for non-resonant signals in dilepton final states at the LHC to use a background estimate from the data. The data, corresponding to an integrated luminosity of 139 fb$^{-1}$, were recorded by the ATLAS experiment in proton-proton collisions at a center-of-mass energy of $\sqrt{s} = 13$ TeV during Run 2 of the Large Hadron Collider. The benchmark signal signature is a two-quark and two-lepton contact interaction, which would enhance the dilepton event rate at the TeV mass scale. To model the contribution from background processes a functional form is fit to the dilepton invariant-mass spectra in data in a mass region below the region of interest. It is then extrapolated to a high-mass signal region to obtain the expected background there. No significant deviation from the expected background is observed in the data. Upper limits at 95 % CL on the number of events and the visible cross-section times branching fraction for processes involving new physics are provided. Observed (expected) 95 % CL lower limits on the contact interaction energy scale reach 35.8 (37.6) TeV.

description: The ground state ensemble of the highly frustrated pyrochlore-lattice antiferromagnet can be mapped to a coarse-grained ``polarization'' field satisfying a zero-divergence condition From this it follows that the correlations of this field, as well as the actual spin correlations, decay with separation like a dipole-dipole interaction ($1/|R|^3$). Furthermore, a lattice version of the derivation gives an approximate formula for spin correlations, with several features that agree well with simulations and neutron-diffraction measurements of diffuse scattering, in particular the pinch-point (pseudo-dipolar) singularities at reciprocal lattice vectors. This system is compared to others in which constraints also imply diffraction singularities, and other possible applications of the coarse-grained polarization are discussed.

description: This article aims the comparison of LSMS survey in Central American countries to increase current knowledge of survey methodologies and ensure the most efficient dissemination and utilization of the results. It is improve the availability, quality and relevance of agricultural data for policy and research in Central America. The criterion for this comparison consists of household survey data production, methodological validation/research, capacity building and dissemination. The integrated approach considers multi-topic questionnaire as agriculture plus non-farm, nutrition, inter alia, consumption –based welfare measure, global strategy to improve Ag statistics. The methodological validation/research is an extension of LSMS IV for improvement of following measures: crop yields (plot size, quantities, measurement tool, diaries/crop cards, crop cutting), module development/sourcebooks (income source, fishery, livestock, and community governance/empowerment. The results would have the following priorities and principles: a) Support and build longitudinal data systems that improve policy decision making, resource allocation, and priority setting, b) Ensure free public access to all data as soon as possible, c) Lower the costs of using data trough data access platforms, harmonization of methodologies, and through outreach and capacity building, d) Capitalize on synergies from integrating different types of data (e.g. broad representative surveys as LSMS, more intensive surveys/sentinel sites, censuses, geospatial data, etc.).

description: In this work the open-plus-closed-loop (OPCL) method of synchronization is used in order to synchronize the systems from the Sprott's collection of the simplest chaotic systems. The method is general and we were looking for the simplest coupling between master and slave system. The interval of parameters were synchronization is achieved are obtained analytically using Routh-Hurwitz conditions. Detailed calculations and numerical simulation are given for the system I from the Sprott's collection. Working in the same manner for non-linear systems based on ordinary differential equations the method can be adopted for the teaching of the topic.

description: This report is an empirical analysis of the effectiveness of the marketing/promotion, nonagricultural research, and agricultural research activities associated with the cotton checkoff program over the period of 1986/87 through 2004/05. The analysis is based on a multi-equation, econometric, non-spatial, price equilibrium simulation model of U.S. and foreign fiber markets using annual data. The key average annual impacts of the cotton checkoff program on U.S. and foreign cotton and man-made fiber markets and their associated textile markets are reported. The results show that the returns to cotton producers as well as to cotton importers from the cotton checkoff program are positive. The average discounted benefit-cost ratios (BCR) for the cotton checkoff program were found to be 5.7 for domestic cotton producers and 14.4 for importers. The higher BCR for importers reflects revenue gains not only from additional sales of cotton fiber textiles but also from additional “spillover” sales of man-made fiber textiles prompted by the cotton checkoff program. The results also show that U.S. taxpayers are better off because the cotton checkoff program has tended to reduce government outlays directed to cotton farmers. The analysis also finds that neither U.S. producers nor importers pay the full cost of the checkoff assessments. Finally, cotton checkoff expenditures on agricultural research were found to have positively and significantly affected U.S. cotton yields with no discernible effects on cotton harvested acreage.
Placemaking, sites of cultural difference : the cultural production of space within a University construct
Creators: name: Archibald, Diane
Publisher: name: University of British Columbia
Year: 2009

description: This inquiry investigates the cultural meaning of architecture, and the notion that different cultures produce and experience space differently. This investigation focuses on cultural issues of space and place as related to ethnicity, gender and their combination. The site of inquiry is the University of British Columbia, a postsecondary educational institution founded on philosophies, ideologies, and values grounded in British scholastic traditions. The university, which is situated on traditional Musqueam land, and which has a large student population representative of diverse cultures, provides a unique site of study. Within the institutionalized spaces of the university, alternative educational spaces have emerged and coexist. For the purpose of this inquiry the university is considered as the dominant norm with the three alternative sites representative of cultures of difference. The alternative sites included in the study are the Centre for Studies in Curriculum Instruction, the First Nations House of Learning, and the Centre for Research in Women's Studies and Gender Relations. The institutionalized spaces of the university are not experienced by all cultures in the same way. They are viewed as Western cultural constructs of space that differ from and are often incommensurable with cultures of difference. Given the cultural location of the user of the space, based on ethnicity and, or gender, the institutionalized spaces of the university are experienced differently. The objectives of this investigation are: to view knowledge as a spatial construct; to view the differences of cultural constructs of space as to race, ethnicity and gender within educational sites; and to view the multiplicity of the cultural meanings of a space given the cultural location of the observer moving through that space. The methodological approach applied to this study is a discursive historical spatial analysis inclusive of architectural drawings, conceptual drawings and plans, maps, archival research, on-site spatial analysis, and participant meetings with users and "conceptualizers" of the respective sites. Although each alternative site is representative of cultural differences, diverse philosophical processes and spatial practices, commonalties emerged such as notions of cultural inclusion, embracing difference, alternative ways of knowing, alternative ways of constructing knowledge, repositioning "other," community, placemaking, and creating a spirit of place.
Dynamical Fermionization in One Dimensional Spinor Gases

description: Dynamical fermionization refers to the phenomenon in Tonks-Girardeau (TG) gases where, upon release from harmonic confinement, the gas's momentum density profile evolves asymptotically to that of an ideal Fermi gas in the initial trap. This phenomenon has been demonstrated theoretically in hardcore and anyonic TG gases, and recently experimentally observed in a strongly interacting Bose gas. We extend this study to a one dimensional (1D) spinor gas of arbitrary spin in the strongly interacting regime, and analytically prove that the total momentum distribution after the harmonic trap is turned off approaches that of a spinless ideal Fermi gas, while the asymptotic momentum distribution of each spin component takes the same shape of the initial real space density profile of that spin component. Our work demonstrates the rich physics arising from the interplay between the spin and the charge degrees of freedom in a spinor system.

description: The measurement of hydrogen induced changes on the electronic structure of transition metal oxides by X-ray photoelectron spectroscopy is a challenging endeavor, since the origin of the photoelectron cannot be unambiguously assigned to hydrogen. The H-induced electronic structure changes in tungsten trioxide have been known for more than 100 years, but are still being controversially debated. The controversy stems from the difficulty in disentangling effects due to hydrogenation from the effects of oxygen deficiencies. Using a membrane approach to X-ray photoelectron spectroscopy, in combination with tuneable synchrotron radiation we measure simultaneously core levels and valence band up to a hydrogen pressure of 1000 mbar. Upon hydrogenation, the intensities of the W$^{5+}$ core level and a state close to the Fermi level increase following the pressure-composition isotherm curve of bulk H$_x$WO$_3$. Combining experimental data and density-functional theory the description of the hydrogen induced coloration by a proton polaron model is corroborated. Although hydrogen is the origin of the electronic structure changes near the Fermi edge, the valence band edge is now dominated by tungsten orbitals instead of oxygen as is the case for the pristine oxide having wider implication for its use as (photo-electrochemical) catalyst.

description: With the reported observation of the Higgs boson at the LHC, the Standard Model of particle physics seems to be complete now as for its particle content. However, several experimental data at low and intermediate energies indicate that there may be two surprises. First we propose a tentative new boson $Z_0(57)$, with a mass of about 57 GeV, on the basis of small enhancements we observe in several experiments, using recent data obtained at the LHC as well as much older ones from LEP. If confirmed, we interpret this new particle as a pseudoscalar or scalar partner of a composite $Z$ vector boson. Secondly, we advocate the existence of a very light spinless boson $E(38)$, probably a scalar, with a mass of 38 MeV and decaying into two photons. Theoretical arguments and experimental signals supporting such a novel light boson will be presented, including a recent direct experimental confirmation at the Joint Institute for Nuclear Research in Dubna.

description: Few examples of magnetic systems displaying a transition to pure dipolar magnetic order are known to date, and single-molecule magnets can provide an interesting example. The molecular cluster spins and thus their dipolar interaction energy can be quite high, leading to reasonably accessible ordering temperatures, provided the crystal field anisotropy is sufficiently small. This condition can be met for molecular clusters of sufficiently high symmetry, as for the Mn6 compound studied here. Magnetic specific heat and susceptibility experiments show a transition to ferromagnetic dipolar order at T_{c} = 0.16 K. Classical Monte-Carlo calculations indeed predict ferromagnetic ordering and account for the correct value of T_{c}. In high magnetic fields we detected the contribution of the ^{55}Mn nuclei to the specific heat, and the characteristic timescale of nuclear relaxation. This was compared with results obtained directly from pulse-NMR experiments. The data are in good mutual agreement and can be well described by the theory for magnetic relaxation in highly polarized paramagnetic crystals and for dynamic nuclear polarization, which we extensively review. The experiments provide an interesting comparison with the recently investigated nuclear spin dynamics in the anisotropic single molecule magnet Mn12-ac.

description: This paper provides a tutorial overview over recent vigorous efforts to develop computing systems based on spin waves instead of charges and voltages. Spin-wave computing can be considered as a subfield of spintronics, which uses magnetic excitations for computation and memory applications. The tutorial combines backgrounds in spin-wave and device physics as well as circuit engineering to create synergies between the physics and electrical engineering communities to advance the field towards practical spin-wave circuits. After an introduction to magnetic interactions and spin-wave physics, all relevant basic aspects of spin-wave computing and individual spin-wave devices are reviewed. The focus is on spin-wave majority gates as they are the most prominently pursued device concept. Subsequently, we discuss the current status and the challenges to combine spin-wave gates and obtain circuits and ultimately computing systems, considering essential aspects such as gate interconnection, logic level restoration, input-output consistency, and fan-out achievement. We argue that spin-wave circuits need to be embedded in conventional CMOS circuits to obtain complete functional hybrid computing systems. The state of the art of benchmarking such hybrid spin-wave--CMOS systems is reviewed and the current challenges to realize such systems are discussed. The benchmark indicates that hybrid spin-wave--CMOS systems promise ultralow-power operation and may ultimately outperform conventional CMOS circuits in terms of the power-delay-area product. Current challenges to achieve this goal include low-power signal restoration in spin-wave circuits as well as efficient spin-wave transducers.

description: AbstractIntroduction Among patients admitted to an emergency department, dyspnoea is one of the most common symptoms. Patients with dyspnoea have high mortality and morbidity. Therefore, novel methods to monitor the patients are warranted. The aim is to investigate whether therapy guided by monitoring patients with acute dyspnoea with serial ultrasound examinations of the heart and the lungs together with standard care can change the severity of dyspnoea compared with treatment guided by standard monitoring alone.Methods and analysis The study will be conducted as a multicentre, randomised, pragmatic, open-label and controlled trial where patients admitted with acute dyspnoea to an emergency ward will be randomised into a standard care group and a serial ultrasound group with 103 patients in each. All patients will be examined with an ultrasound of the heart and the lungs upfront. In addition, the patients in the serial ultrasound group will be examined with an ultrasound of the heart and lungs two more times to guide further therapy during the admittance. The primary outcome is a change in dyspnoea on a verbal scale. After discharge, the patients are followed for 1 year to assess the number of readmissions, death and length of hospital stay.Ethics and dissemination The trial is conducted in accordance with the Declaration of Helsinki and approved by The Regional Committee on Health Research Ethics for Region Zealand, Denmark (identifier SJ-744). Data handling agreement with participating centres has been made (identifier REG-056–2019). The General Data Protection Regulation and the Danish Data Protection Act will be respected. The results of the trial will be reported in peer-reviewed scientific journals regardless of the outcomes.Trial registration number NCT04091334http://creativecommons.org/licenses/by-nc/4.0/This is an open access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited, appropriate credit is given, any changes made indicated, and the use is non-commercial.

The elusive quest for statehood : fundamental issues of the state, political cultures and aliran politics in Indonesia
Creators: name: Lanti, Irman G.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis discusses the difficulties faced by the Indonesian state in its attempt to achieve a stable statehood. Three fundamental and unresolved issues have vexed the Indonesian state since the inception of the nationalist movement at the turn of last century: the state foundation (the choice between a secular arrangement or an Islamic state), regionalism (a governmental arrangement dominated by the center or a devolution of power to the regions/districts), and the degree of political competition (an authoritarian state or an open political system). Indonesia is a plural society, with hundreds of ethnic groups, speaking hundreds of languages and dialects. But throughout its history, the ethnic fault line has generally been drawn between the Javanese and the (seberang) outer islanders. The geographic distinction between the agricultural Javanese and the maritime seberang, coupled with the different extent of influence of Hindu- Buddhism, as well as Islam later on, have created divergent politico-cultural traits among these groups. These ethno-religious groups eventually manifested themselves into political groups. Earlier scholars of Indonesian studies, such as Clifford Geertz and Herbert Feith, called these groups the political aliran. There are three major aliran in Indonesia: the nationalists (Javanese-based nominal Muslims), the modernist Muslims (seberang-based purist, reformist Muslims), and the traditionalist Muslims (Javanese-based pious Muslims). Each of these groups has a major political party, supported by a network of mass social institutions, and each holds a distinctive view on the fundamental issues of statehood. Indonesian history has seen the ebb and flow of the aliran. After the heyday of "aliranism" in the 1950s, Sukarno and Suharto carried out "de-aliranization" measures in the name of "national unity", which lasted until the outbreak of Reformasi. The reform movement that helped push Suharto from office brought about a resurgence of aliran politics that had been in a state of hibernation for almost four decades. All of the important political parties that have arisen since 1998 have had an aliran cast or shape. The resurgence of the aliran has also marked a return of the debates on the three fundamental issues of the state mentioned above. This thesis has found some reasons why the resurgence of these aliran has complicated the efforts at democratization in Indonesia. All three aliran and their parties profess to want "democracy". But their respective understandings of democracy are different when it comes to the three key issues that have vexed Indonesia throughout its history.
Discriminating the HTM and MLRSM models in collider studies via doubly charged Higgs boson pair production and the subsequent leptonic decays

description: We present a case study for the doubly charged Higgs bosons $H^{\pm\pm}$ pair production in $e^+e^-$ and $pp$ colliders with their subsequent decays to four charged leptons. We consider the Higgs Triplet Model (HTM) not restricted by the custodial symmetry and the Minimal Left-Right Symmetric Model (MLRSM). The models include scalar triplets with different complexity of scalar potentials and, due to experimental restrictions, completely different scales of non-standard triplet vacuum expectation values. In both models, a doubly charged Higgs boson $H^{\pm\pm}$ can acquire a mass of hundreds of gigaelectronvolts, which can be probed at HL-LHC, future $e^+e^-$, and hadron colliders. We take into account a comprehensive set of constraints on the parameters of both models coming from neutrino oscillations, LHC, $e^+e^-$ and low-energy lepton flavour violating data and assume the same mass of $H^{\pm\pm}$. Our finding is that the $H^{\pm\pm}$ pair production in lepton and hadron colliders is comparable in both models, though more pronounced in MLRSM. We show that the decay branching ratios can be different within both models, leading to distinguishable four lepton signals and that the strongest are $4μ$ events yielded by MLRSM. Typically we find that MLRSM signals are one order of magnitude larger that in HTM. For example, the $pp \to 4μ$ MLRSM signal for 1 TeV $H^{\pm \pm}$ mass results in a clearly detectable significance of $S \simeq 11$ for HL-LHC and $S \simeq 290$ for FCC-hh. Finally we provide quantitative predictions for the dilepton invariant mass distributions and lepton separations which help to identify non-standard signals.

description: The dispersion scan (d-scan) technique has emerged as a simple-to-implement characterization method for ultrashort laser pulses. D-scan traces are intuitive to interpret and retrieval algorithms that are both fast and robust have been developed to obtain the spectral phase and the temporal pulse profile. Here, we give a review of the d-scan technique based on second harmonic generation. We describe and compare recent implementations for the characterization of few- and multi-cycle pulses as well as two different approaches for recording d-scan traces in single-shot, thus showing the versatility of the technique.

description: In 2001 the World Trade Organization launched a highly ambitious program of multilateral liberalization. Eight years later, concluding the negotiations is uncertain, though an opportunity still exists. Since 2001, many proposals on market access have been brought to the negotiating table by the European Union, the United States, and the G20. Because it is politically and economically acceptable to many parties, the final December 2008 package could be the basis of an agreement. An evaluation of these various proposals shows how trade negotiations have been following countries’ strategic interests. In eight years, the ambition of the formula in agricultural market access tariff reduction has increased, but additional flexibilities designed to accommodate domestic political constraints have offset delivered market access. The various scenarios imply losses for least-developed countries, reflecting eroded preferences and rising terms of trade for imported commodities, including food products. We study how this trade reform can be more development-friendly.

description: The purpose of the paper is to construct a polyhedral Markov field in ${\mathbb R}^3$ in analogy with the planar construction of the original Arak (1982) polygonal Markov field. We provide a dynamic construction of the process in terms of evolution of two-dimensional multi-edge systems tracing polyhedral boundaries of the field in three-dimensional time-space. We also give a general algorithm for simulating Gibbsian modifications of the constructed polyhedral field.

description: Simultaneously cooling the rotational and translational motion of nanoscale dielectrics into the quantum regime is an open task of great importance for sensing applications and quantum superposition tests. Here, we show that the six-dimensional ground state can be reached by coherent-scattering cooling with an elliptically polarized and shaped optical tweezer. We determine the cooling rates and steady-state occupations in a realistic setup and discuss applications for mechanical sensing and fundamental experiments.

Inflation and the cosmological (not-so) constant in unimodular gravity

description: We propose a mechanism for generating an inflationary phase in the early universe without resorting to any type of scalar field(s). Instead, this accelerated expansion is driven by a dynamical "cosmological constant" in the framework of unimodular gravity. The time dependent cosmological constant can be related to an energy diffusion term that arises naturally in unimodular gravity due to its restrictive diffeomorphism invariance. We derive the generic conditions required for any type of diffusion to generate a realistic inflationary epoch. Furthermore, for a given parameterization of inflation (in terms of the Hubble flow functions), we show how to construct the corresponding diffusion term in such a way that a smooth transition occurs between inflation and the subsequent radiation dominated era, hence reheating proceeds naturally. The primordial spectrum is obtained during the inflationary phase by considering inhomogeneous perturbations associated to standard hydrodynamical matter (modeled as a single ultra-relativistic fluid). We demonstrate that the resulting spectrum is equivalent to that obtained in traditional inflationary models, and is also independent of the particular form of the diffusion term. In addition, we analyze the feasibility of identifying the variable cosmological constant, responsible for the inflationary expansion, with the current observed value.

The optical polarization of the blazar PKS 2155$-$304 during an optical flare in 2010

description: An analysis is presented of the optical polarimetric and multicolour photometric ($BVRJ$) behaviour of the blazar PKS 2155$-$304 during an outburst in 2010. This flare develops over roughly 117 days, with a flux doubling time $τ\sim 11$ days that increases from blue to red wavelengths. The polarization angle is initially aligned with the jet axis but rotates by roughly $90^\circ$ as the flare grows. Two distinct states are evident at low and high fluxes. Below 18 mJy, the polarization angle takes on a wide range of values, without any clear relation to the flux. In contrast, there is a positive correlation between the polarization angle and flux above 18 mJy. The polarization degree does not display a clear correlation with the flux. We find that the photopolarimetric behaviour for the high flux state can be attributed to a variable component with a steady power-law spectral energy distribution and high optical polarization degree (13.3%). These properties are interpreted within the shock-in-jet model, which shows that the observed variability can be explained by a shock that is seen nearly edge-on. Some parameters derived for the relativistic jet within the shock-in-jet model are: $B=0.06$ G for the magnetic field, $δ=22.3$ for the Doppler factor and $Φ=2.6^\circ$ for the viewing angle.

Continuous Time Monte Carlo and Spatial Ordering in Driven Lattice Gases: Application to Driven Vortices in Periodic Superconducting Networks

description: We consider the two dimensional (2D) classical lattice Coulomb gas as a model for magnetic field induced vortices in 2D superconducting networks. Two different dynamical rules are introduced to investigate driven diffusive steady states far from equilibrium as a function of temperature and driving force. The resulting steady states differ dramatically depending on which dynamical rule is used. We show that the commonly used driven diffusive Metropolis Monte Carlo dynamics contains unphysical intrinsic randomness that destroys the spatial ordering present in equilibrium (the vortex lattice) over most of the driven phase diagram. A continuous time Monte Carlo (CTMC) is then developed, which results in spatially ordered driven states at low temperature in finite sized systems. We show that CTMC is the natural discretization of continuum Langevin dynamics, and argue that it gives the correct physical behavior when the discrete grid represents the minima of a periodic potential. We use detailed finite size scaling methods to analyze the spatial structure of the steady states. We find that finite size effects can be subtle and that very long simulation times can be needed to arrive at the correct steady state. For particles moving on a triangular grid, we find that the ordered moving state is a transversely pinned smectic that becomes unstable to an anisotropic liquid on sufficiently large length scales. For particles moving on a square grid, the moving state is a similar smectic at large drives, but we find evidence for a possible moving solid at lower drives. We find that the driven liquid on the square grid has long range hexatic order, and we explain this as a specifically non-equilibrium effect. We show that, in the liquid, fluctuations are diffusive in both the transverse and longitudinal directions.

Transversely isotropic cyclic stress-softening model for the Mullins effect

description: This paper models stress softening during cyclic loading and unloading of an elastomer. The paper begins by remodelling the primary loading curve to include a softening function and goes on to derive non-linear transversely isotropic constitutive equations for the elastic response, stress relaxation, residual strain and creep of residual strain. These ideas are combined with a transversely isotropic version of the Arruda-Boyce eight-chain model to develop a constitutive relation that is capable of accurately representing the Mullins effect during cyclic stress-softening for a transversely isotropic, hyperelastic material, in particular a carbon-filled rubber vulcanizate. Keywords: Mullins effect, stress-softening, hysteresis, stress relaxation, residual strain, creep of residual strain, transverse isotropy. MSC codes: 74B20, 74D10, 74L15
