Search for heavy particles decaying into a top-quark pair in the fully hadronic final state in $pp$ collisions at $\sqrt{s} =13$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration

description: A search for new particles decaying into a pair of top quarks is performed using proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of $\sqrt{s} = $13 TeV corresponding to an integrated luminosity of 36.1 fb$^{-1}$. Events consistent with top-quark pair production and the fully hadronic decay mode of the top quarks are selected by requiring multiple high transverse momentum jets including those containing $b$-hadrons. Two analysis techniques, exploiting dedicated top-quark pair reconstruction in different kinematic regimes, are used to optimize the search sensitivity to new hypothetical particles over a wide mass range. The invariant mass distribution of the two reconstructed top-quark candidates is examined for resonant production of new particles with various spins and decay widths. No significant deviation from the Standard Model prediction is observed and limits are set on the production cross-section times branching fraction for new hypothetical $Z'$ bosons, dark-matter mediators, Kaluza-Klein gravitons and Kaluza-Klein gluons. By comparing with the predicted production cross-sections, the $Z'$ boson in the topcolor-assisted-technicolor model is excluded for masses up to 3.1$-$3.6 TeV, the dark-matter mediators in a simplified framework are excluded in the mass ranges from 0.8 TeV to 0.9 TeV and from 2.0 TeV to 2.2 TeV, and the Kaluza-Klein gluon is excluded for masses up to 3.4 TeV, depending on the decay widths of the particles.

description: The Bohigas--Giannoni--Schmit conjecture stating that the statistical spectral properties of systems which are chaotic in their classical limit coincide with random matrix theory is proved. For this purpose a new semiclassical field theory for individual chaotic systems is constructed in the framework of the non--linear $σ$-model. The low lying modes are shown to be associated with the Perron--Frobenius spectrum of the underlying irreversible classical dynamics. It is shown that the existence of a gap in the Perron-Frobenius spectrum results in a RMT behavior. Moreover, our formalism offers a way of calculating system specific corrections beyond RMT.

description: We present a search for gamma-ray bursts in the Fermi-GBM 10 year catalog that show similar characteristics to GRB 170817A, the first electromagnetic counterpart to a GRB identified as a binary neutron star (BNS) merger via gravitational wave observations. Our search is focused on a non-thermal pulse, followed by a thermal component, as observed for GRB 170817A. We employ search methods based on the measured catalog parameters and Bayesian Block analysis. Our multi-pronged approach, which includes examination of the localization and spectral properties of the thermal component, yields a total of 13 candidates, including GRB 170817A and the previously reported similar burst, GRB 150101B. The similarity of the candidates is likely caused by the same processes that shaped the gamma-ray signal of GRB 170817A, thus providing evidence of a nearby sample of short GRBs resulting from BNS merger events. Some of the newly identfied counterparts were observed by other space telescopes and ground observatories, but none of them have a measured redshift. We present an analysis of this sub-sample, and we discuss two models. From uncovering 13 candidates during a time period of ten years we predict that Fermi-GBM will trigger on-board on about one burst similar to GRB 170817A per year.

description: We study a random neighbor version of the Bak-Sneppen model, where "nearest neighbors" are chosen according to a probability distribution decaying as a power-law of the distance from the active site, P(x) \sim |x-x_{ac }|^{-ω}. All the exponents characterizing the self-organized critical state of this model depend on the exponent ω. As ωtends to 1 we recover the usual random nearest neighbor version of the model. The pattern of results obtained for a range of values of ωis also compatible with the results of simulations of the original BS model in high dimensions. Moreover, our results suggest a critical dimension d_c=6 for the Bak-Sneppen model, in contrast with previous claims.

Interconnection Effects in Multiparticle Production from WW Events at LEP

Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Interactions between the products of the hadronic decays of different Ws in WW pair events can occur at several stages: from the colour rearrangement between the quarks coming from the primary branching, to the gluon exchange during the parton cascade, to the mixing of identical pions due to Bose-Einstein correlations. Besides the intrinsic interest of their study related to the understanding of the multiparticle production mechanisms, these phenomena can affect the ultimate accuracy in the W mass measurement by LEP 2. The status of the experimental analysis on interconnection effects between W pairs hadronically decaying is reviewed in this paper.

description: Many models containing particles which are candidates for dark matter, assume the standard model particles and the dark matter candidates are mediated by a spin-0 particle. At the LHC, one can use these models for dark matter searches. One of the possible approaches for the search of these models is by considering the decay of the spin-0 particle to a pair of $t\bar{t}$, thus modifying the pattern of the top quark pair invariant mass spectrum. This search suggests a good sensitivity in a parameter space different than the more traditional searches. We examine this sensitivity and put limits on two benchmark models containing candidates for dark matter, using previous ATLAS results. It was found that when the mediator mass ($m_{Y_0}$) and the dark matter candidate mass ($m_χ$) have values of $m_{Y_0} \sim 2 \cdot m_χ$, mediator masses in the range of $[400,600]$ GeV are excluded. We compare our results to direct detection experiments and show that we gain sensitivity for new regions which are not covered by other searches.

description: The gradient of aluminium foam has a significant influence in the performance. This thesis investigates the drainage effect on the gradient of aluminium foam and the accuracy of gradient prediction by mathematics model is improved. Voronoi structure is employed to approximate polyhedral foam structure and the result is consistent with the actual aluminium foam at high porosity. In addition, the damping performance influenced by porosity gradient preliminary explored, finding that local plastic deformation within the overall elastic range may be the primary damping mechanism of aluminium foam.
Interfacial growth morphologies in dense eutectic crystal mushes
Creators: name: Fowler, Andrew

Publisher: name: University of Limerick
Year: 2024

description: We consider the interfacial growth morphologies of crystals growing in contact in crystal mushes, with a specific application to those formed by the solidification of basaltic magma. We focus on the particular case of an augite (pyroxene) crystal growing between two plagioclase crystals. The augite is treated as an equant unfaceted crystal, whereas the plagioclase is faceted, and our treatment applies generally to such combinations. The resulting three-grain junctions in natural rock samples are commonly of two distinct types. In one, the two augite–plagioclase interfaces grow towards each other with opposite curvatures, whereas in the second the curvatures of the interfaces have the same sign, giving a distinctive morphology which we have called an eagle’s beak. This paper provides a theoretical framework to provide explanations for both of these morphologies, based on the kinetics of interfacial growth.

description: In Alzheimer's disease (AD), the progressive atrophy leads to aberrant network reconfigurations both at structural and functional levels. In such network reorganization, the core and peripheral nodes appear to be crucial for the prediction of clinical outcome due to their ability to influence large-scale functional integration. However, the role of the different types of brain connectivity in such prediction still remains unclear. Using a multiplex network approach we integrated information from DWI, fMRI and MEG brain connectivity to extract an enriched description of the core-periphery structure in a group of AD patients and age-matched controls. Globally, the regional coreness - i.e., the probability of a region to be in the multiplex core - significantly decreased in AD patients as a result of the randomization process initiated by the neurodegeneration. Locally, the most impacted areas were in the core of the network - including temporal, parietal and occipital areas - while we reported compensatory increments for the peripheral regions in the sensorimotor system. Furthermore, these network changes significantly predicted the cognitive and memory impairment of patients. Taken together these results indicate that a more accurate description of neurodegenerative diseases can be obtained from the multimodal integration of neuroimaging-derived network data.

description: A low frequency dynamic response of a vortex manifold in type-II superconductor can be associated with thermally activated tunneling of large portions of the manifold between pairs of metastable states (two-level systems). We suggest that statistical properties of these states can be verified by using the same approach for the analysis of thermal fluctuations the behaviour of which is well known. We find the form of the response for the general case of vortex manifold with non-dispersive elastic moduli and for the case of thin superconducting film for which the compressibility modulus is always non-local.

description: We present a method to perform fully selfconsistent density-functional calculations, which scales linearly with the system size and which is well suited for very large systems. It uses strictly localized pseudoatomic orbitals as basis functions. The sparse Hamiltonian and overlap matrices are calculated with an $O(N)$ effort. The long range selfconsistent potential and its matrix elements are computed in a real-space grid. The other matrix elements are directly calculated and tabulated as a function of the interatomic distances. The computation of the total energy and atomic forces is also done in $O(N)$ operations using truncated, Wannier-like localized functions to describe the occupied states, and a band-energy functional which is iteratively minimized with no orthogonality constraints. We illustrate the method with several examples, including carbon and silicon supercells with up to 1000 Si atoms and supercells of $β$-C$_3$N$_4$. We apply the method to solve the existing controversy about the faceting of large icosahedral fullerenes by performing dynamical simulations on C$_{60}$, C$_{240}$, and C$_{540}$.

description: The actin cortex is a thin layer of actin filaments and myosin motors beneath the outer membrane of animal cells. It determines the cells' mechanical properties and forms important morphological structures. Physical descriptions of the cortex as a contractile active gel suggest that these structures can result from dynamic instabilities. However, in these analyses the cortex is described as a two-dimensional layer. Here, we show that the dynamics of the cortex is qualitatively different when gel fluxes in the direction perpendicular to the membrane are taken into account. In particular, an isotropic cortex is then stable for arbitrarily large active stresses. If lateral contractility exceeds vertical contractility, the system can either from protrusions with an apparently chaotic dynamics or a periodic static pattern of protrusions.

description: In the frame of the VEGA-E preparation programme to improve the competitiveness of VEGA launch service, AVIO is developing a new 10 Tons liquid cryogenic rocket engine called M10. The present work outlines the development status of the M10 rocket engine. The reference configuration for this engine is a full expander cycle using liquid oxygen and methane as propellants; the use of innovative technologies for the upper stage engine will enable the increase of competitiveness of VEGA -E through the reduction of the launch service costs and increase of flexibility. After having performed the Step 1 of the Preliminary Design Review (PDR) at engine level, the development of main engine subsystems (e.g. turbopumps, valves, cardan, igniter, ...) is ongoing and contributes to the design of the first Development Model (DM1) which will be manufactured by end 2019 and sub ject to hot firing tests. Regarding the core new development of the Thrust Chamber Assembly (TCA), a trade -off between the conventional bi-metallic nickel-copper manufacturing approach and an innovative design based on Additive Layer Manufacturing (ALM) is conducted, based on sub-scale hot firing tests of both configurations. At beginning of second semester of 2019, ALM TCA full scale autonomous testing will take place and the choice will be reflected also for DM1 engine configuration. The engine tests will consolidate the development of the engine looking for the best compromise between performances, recurring costs, reliability and development risks.

description: Multi-Robot systems for Space exploration are an interesting alternative versus traditional large monolithic rovers in terms of performance and reliability. However, for a community of cooperative autonomous robots to achieve complex exploration goals, a solid infrastructure of communications and location determination (as a supporting resource for navigation through the scenario) must exist in advance, which traditionally is built over radiofrequencybased technologies due to its robustness and suitability for extreme environmental conditions, such as in typical Space exploration scenarios. This contribution discusses on the impact of electronic oscillators phase noise in the error introduced in the relative location and velocity determination based on frequency measurement techniques, such as Frequency of Arrival (FoA) or Frequency Difference of Arrival (FDoA). A noise model is obtained for a hypothetic scenario consisting in a system for position and relative speed determination on a lunar surface exploration mission, where different options for local oscillators are proposed, considering practical aspects such as size, volume and power consumption against phase noise. The impact of the phase noise in global velocity and position error is determined, analysed and discussed for different commercial oscillators and configurations.

description: Due to the rapid growth of the World Wide Web, resource discovery becomes an increasing problem. As an answer to the demand for information management, a third generation of World-Wide Web tools will evolve: information gathering and processing agents. This paper describes WAVE (Web Analysis and Visualization Environment), a 3D interface for World-Wide Web information visualization and browsing. It uses the mathematical theory of concept analysis to conceptually cluster objects, and to create a three-dimensional layout of information nodes. So-called "conceptual scales" for attributes, such as location, title, keywords, topic, size, or modification time, provide a formal mechanism that automatically classifies and categorizes documents, creating a conceptual information space. A visualization shell serves as an ergonomically sound user interface for exploring this information space.

description: We examine transport in a holographic model which describes, through a nonlinear gauge field sector, generic nonlinear interactions between the charge carriers. Scaling exponents are introduced by using geometries which are nonrelativistic and hyperscaling-violating in the infrared. In the dilute charge limit in which the gauge field sector does not backreact on the geometry, a particularly simple nonlinear theory reproduces the anomalous temperature dependence of the resistivity and Hall angle of the cuprate strange metals, $R \sim T$ and $\cotΘ_H \sim T^2$ while also allowing for a linear entropy $S \sim T$, and predicts that the magnetoresistance for small values of the magnetic field $h$ should scale as $\sim h^2 T^{-4}$. Our study lends evidence to the idea that the strange metal behavior of the cuprates relies crucially on the linear temperature dependence of the entropy.

description: We present a detailed analysis of the $D \to V γ$ transitions, using a model which combines heavy quark effective theory and the chiral Lagrangian approach and includes symmetry breaking. We notice that in addition to the previously considered s - channel annihilation and t - channel W - exchange, there is a long distance penguin - like $ c \to u γ$ contribution in the t - channel of Cabibbo - suppressed modes. Its magnitude is determined by the size of symmetry breaking which we calculate with a vector dominance approach. Although smaller in magnitude, the penguin - like contribution would lead to sizeable effects in case of cancellations among the other contributions to the amplitude. Thus, it may invalidate suggested tests for beyond the standard model effects in these decays. We also indicate the range of expectations for the branching ratios of various $D \to V γ$ modes.

description: As a new Librarian straight out of my MSIS program, I am seeing a shift in the idea of what constitutes the position of “Cataloging Librarian.” As a student worker at UT Austin while in library school, and in my current position as Cataloging Librarian at Binghamton University, I have seen in both places a rising discussion of how cataloging should evolve to keep up with the reframing and rebranding that is taking place throughout all aspects of libraries and librarianship. A common answer that seems to be rising is that cataloging is and needs to continue its reframing to include the newer, broader field of metadata. So, we see cataloging practices shifting to include metadata projects such as digitization. The presentation I am proposing would discuss this reframing of cataloging as a merger between the traditional idea of cataloging and the new area of “metadata.” I would like to use the research I have been conducting with a partner for a journal article as the starting point for my presentation. I have recently begun, with a partner, research for an article in which we wanted to explore how difficult it was for college and university affiliated academic libraries to fill advertised cataloging positions. We gathered data on such advertised positions from the years 2014-2016, so we have two years worth of advertisements. Initially we included in our dataset only advertisements that described positions that involved cataloging at least 50% of the time. We tried to create a sizeable dataset from advertisements that included “cataloging” specifically in the title as well. However, in compiling this list and looking at the job descriptions we realized we would not have a large enough dataset for our article unless we included jobs that referenced not only cataloging, but also metadata duties in at least equal measure. Many advertised positions required cataloging and metadata components, leading to the topic of my proposed presentation. I would like to present on how, to keep up with 21st century trends, the field of cataloging is merging with and being folded into the new field of metadata, and how this is causing cataloging jobs to be reframed as well.

description: The European Space Agency (ESA) Science Programme Committee (SPC) selected CHEOPS (Characterizing Exo-planets Satellite) in October 2012 as the first S-class mission (S1) within the Agency\'s Scientific Programme, targeting launch readiness by the end of 2018. The CHEOPS mission is devoted to the first-step characterization of known exoplanets orbiting bright stars, to be achieved through the precise measurement of exo-planet radii using the technique of transit photometry. It is implemented as a partnership between ESA and a consortium of Member States led by Switzerland. CHEOPS is considered as a pilot case for implementing \"small science missions\" in ESA with the following requirements: science driven missions selected through an open Call for missions (bottom-up process); spacecraft development schedule much shorter than for M (medium) and L (large) missions, in the range of 4 years; and cost-capped missions to ESA with possibly higher Member States involvement than for M or L missions. To reach its scientific goal of accurately characterizing exoplanet sizes, CHEOPS instrument will measure photometric signals with a precision of 20 ppm in 6 hours of integration time for a 9th magnitude star and a precision of 85 ppm in 3 hours integration time for Neptune-size planets orbiting 12th magnitude star. By being able to point at large portion of the sky, with 50% of the whole sky accessible for 50 cumulative days of observations per year, CHEOPS will provide the unique capability of determining accurate radii for a subset of those planets for which the mass has already been estimated from ground-based Doppler surveys. The instrument provided by a consortium led by the University of Bern is an optical Ritchey-Chretien telescope with 300 mm effective aperture diameter, which provides a defocussed image of the target star on a single frame-transfer backside illuminated CCD detector. Straylight is minimized using a large external baffle and a dedicated field stop. AIRBUS DS Spain was awarded with the contract to manufacture and integrate the satellite platform, the integration of the scientific instrument, the realization of the satellite functional and environmental campaigns, the launch campaign and the LEOP (lunch and early operation phase) and IOC (in orbit commissioning) phases. The platform is based on heritage from AS250, which is a compact, high performance and flight proven design. The paper reports the Cheops satellite readiness for flight, including instrument calibration and spacecraft environmental test campaign and the preparation for launch which is planned for November 2019 on a shared Soyuz launcher.
The quantum superalgebra $U_q[osp(1/2n)]$: deformed para-Bose operators and root of unity representations

description: We recall the relation between the Lie superalgebra $osp(1/2n)$ and para-Bose operators. The quantum superalgebra $U_q[osp(1/2n)]$, defined as usual in terms of its Chevalley generators, is shown to be isomorphic to an associative algebra generated by so-called pre-oscillator operators satisfying a number of relations. From these relations, and the analogue with the non-deformed case, one can interpret these pre-oscillator operators as deformed para-Bose operators. Some consequences for $U_q[osp(1/2n)]$ (Cartan-Weyl basis, Poincaré-Birkhoff-Witt basis) and its Hopf subalgebra $U_q[gl(n)]$ are pointed out. Finally, using a realization in terms of ``$q$-commuting'' $q$-bosons, we construct an irreducible finite-dimensional unitary Fock representation of $U_q[osp(1/2n)]$ and its decomposition in terms of $U_q[gl(n)]$ representations when $q$ is a root of unity.

description: The structural, physical, and mechanical properties of aluminium after laser-induced shock peening (LSP) were investigated before and after depositing films of various metals (Cu, In, and Al). The deposition of single and double films was conducted, and the physical property (density), shockwave properties (shock pressure, particle velocity, and shock velocity), mechanical properties (stress, strain, Young's s modulus, and Hardness) were calculated, Young's s modulus measured of aluminum was measured by classical method (Tensile test) and by LSP technique, and it was found that the measured using LSP is closer to the standard value than classical method. Single film Cu and sandwich Al / Cu deposited on Al substrate showed an enhancement in the mechanical properties rather than other films, while the deposited films of (In, In / Cu, and Al /In) on Al substrate revealed more strain and higher ductility than others. The laser-induced shock wave has a great importance in viruses, industrial and medical applications.

description: Gravitationally lensed quasars are valuable, but extremely rare, probes of observational cosmology and extragalactic astrophysics. Progress in these fields has been limited just by the paucity of systems with good ancillary data. Here we present a first spectroscopic confirmation of lenses discovered in the Southern Sky from the DES and KiDS-DR3 footprints. % optical ground based surveys in the Southern Hemisphere. We have targeted 7 high-graded candidates, selected with new techniques, with NTT-EFOSC2, and confirmed 5 of them. We provide source spectroscopic redshifts, image separations, $gri$ photometry and first lens model parameters. The success rate of ~70% confirms our forecasts, based on the comparison between the number of candidate doubles and quadruplets in our searches over a ~5000 sq.deg footprint and theoretical predictions.

description: This paper presents the results of experimental investigations for the thermal qualification of radomes for high-speed missiles made of the oxide ceramic matrix composites WHIPOX and OXIPOL with different types of thermal insulation based on silica aerogels. Experiments were conducted in a blowdown windtunnel for aerothermodynamic investigations at Mach 3 flight conditions and in an archeated windtunnel at flight-relevant heat loads of higher Mach numbers derived from sample trajectories. Thermocouples and infrared thermography were used to measure the temperature distribution on the interior and exterior surfaces of the radome and the heating of a seeker head demonstrator.

description: We derive the four-point correlators of scalar operators of dimension one in the supergravity limit of the D1D5 CFT holographically dual to string theory on AdS$_3\times S^3\times \mathcal{M}$, with $\mathcal{M}$ either $T^4$ or $K3$. We avoid the use of Witten diagrams but deduce our result from a limit of the heavy-heavy-light-light correlators computed in arXiv:1705.09250, together with several consistency requirements of the OPE in the various channels. This result represents the first holographic correlators of single-trace operators computed in AdS$_3$.

description: We present a theoretical analysis of the effect of dielectric confinement on the Coulomb interaction in dielectrically modulated quantum structures. We discuss the implications of the strong enhancement of the electron-hole and electron-electron coupling for two specific examples: (i) GaAs-based quantum wires with remote oxide barriers, where combined quantum and dielectric confinements are predicted to lead to room temperature exciton binding, and (ii) semiconductor quantum dots in colloidal environments, where the many-body ground states and the addition spectra are predicted to be drastically altered by the dielectric environment.

A Distance Map Regularized CNN for Cardiac Cine MR Image Segmentation

description: Cardiac image segmentation is a critical process for generating personalized models of the heart and for quantifying cardiac performance parameters. Several convolutional neural network (CNN) architectures have been proposed to segment the heart chambers from cardiac cine MR images. Here we propose a multi-task learning (MTL)-based regularization framework for cardiac MR image segmentation. The network is trained to perform the main task of semantic segmentation, along with a simultaneous, auxiliary task of pixel-wise distance map regression. The proposed distance map regularizer is a decoder network added to the bottleneck layer of an existing CNN architecture, facilitating the network to learn robust global features. The regularizer block is removed after training, so that the original number of network parameters does not change. We show that the proposed regularization method improves both binary and multi-class segmentation performance over the corresponding state-of-the-art CNN architectures on two publicly available cardiac cine MRI datasets, obtaining average dice coefficient of 0.84$\pm$0.03 and 0.91$\pm$0.04, respectively. Furthermore, we also demonstrate improved generalization performance of the distance map regularized network on cross-dataset segmentation, showing as much as 42% improvement in myocardium Dice coefficient from 0.56$\pm$0.28 to 0.80$\pm$0.14.

Dynamic Shortening of Disorder Potentials in Anharmonic Halide Perovskites

description: Halide perovskites are semiconductors that exhibit sharp optical absorption edges and small Urbach energies allowing for efficient collection of sunlight in thin-film photovoltaic devices. However, halide perovskites also exhibit large nuclear anharmonic effects and disorder, which is unusual for efficient optoelectronic materials and difficult to rationalize in view of the small Urbach energies that indicate a low amount of disorder. To address this important issue, the disorder potential induced for electronic states by the nuclear dynamics in various paradigmatic halide perovskites is studied with molecular dynamics and density functional theory. We find that the disorder potential is dynamically shortened due to the nuclear motions in the perovskite, such that it is short-range correlated, which is shown to lead to favorable distributions of band edge energies. This dynamic mechanism allows for sharp optical absorption edges and small Urbach energies, which are highly desired properties of any solar absorber material.
