Pascuzzi, Kwangmin Yu Categories: hep-ex cs.DC Comments: 15 pages, 1 figure, 6 tables, 2 listings, submitted to Frontiers in Big Data (Big Data in AI and High Energy Physics) \\ The High Energy Physics (HEP) experiments, such as those at the Large Hadron Collider (LHC), traditionally consume large amounts of CPU cycles for detector simulations and data analysis, but rarely use compute accelerators such as GPUs. As the LHC is upgraded to allow for higher luminosity, resulting in much higher data rates, purely relying on CPUs may not provide enough computing power to support the simulation and data analysis needs. As a proof of concept, we investigate the feasibility of porting a HEP parameterized calorimeter simulation code to GPUs. We have chosen to use FastCaloSim, the ATLAS fast parametrized calorimeter simulation. While FastCaloSim is sufficiently fast such that it does not impose a bottleneck in detector simulations overall, significant speed-ups in the processing of large samples can be achieved from GPU parallelization at both the particle (intra-event) and event levels; this is especially beneficial in conditions expected at the high-luminosity LHC, where an immense number of per-event particle multiplicities will result from the many simultaneous proton-proton collisions. We report our experience with porting FastCaloSim to NVIDIA GPUs using CUDA. A preliminary Kokkos implementation of FastCaloSim for portability to other parallel architectures is also described. \\ ( https://arxiv.org/abs/2103.14737 , 55kb) ------------------------------------------------------------------------------ \\ arXiv:2103.14772 Date: Fri, 26 Mar 2021 23:53:56 GMT (203kb,D) Title: Measurements of top-quark pair and single top total cross sections, and in-situ systematic constraints Authors: Olga Bessidskaia Bylund Categories: hep-ex Comments: Presented at the 13th International Workshop on Top Quark Physics, Durham, UK (videoconference), 14-18 September, 2020 on behalf of the ATLAS and CMS collaborations \\ Measuring the total cross sections of top-quark pair production and single top processes at high precision tests the predictions of the Standard Model and can bring better understanding of properties such as the top-quark mass, electroweak couplings, lepton universality and proton parton distribution functions. Some of the recent measurements by the ATLAS and CMS experiments at the Large Hadron Collider are outlined in this document. Experimental methods are given particular attention, particularly the determination of lepton isolation efficiencies in the ATLAS dilepton measurement of top-quark pair production. \\ ( https://arxiv.org/abs/2103.14772 , 203kb) ------------------------------------------------------------------------------ \\ arXiv:2103.15098 Date: Sun, 28 Mar 2021 09:57:36 GMT (1184kb,D) Title: Amplitude analysis and branching-fraction measurement of \boldmath $D_{s}^{+} \to K^0_{S}\pi^{+}\pi^{0}$ Authors: BESIII Collaboration: M.

(425 additional authors not shown) Categories: hep-ex \\ Utilizing a data set corresponding to an integrated luminosity of 6.32~$\rm fb^{-1}$, recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226~GeV, we perform an amplitude analysis of the decay $D_{s}^{+} \to K_{S}^{0}\pi^{+}\pi^{0}$ and determine the relative fractions and phase differences of different intermediate processes, which include $K_{S}^{0}\rho(770)^{+}$, $K_{S}^{0}\rho(1450)^{+}$, $K^{*}(892)^{0}\pi^{+}$, $K^{*}(892)^{+}\pi^{0}$, and $K^{*}(1410)^{0}\pi^{+}$. Using a double-tag technique, and making an efficiency correction that relies on our knowledge of the phase-space distribution of the decays coming from the amplitude analysis, the absolute branching fraction is measured to be $\mathcal{B}(D_{s}^{+} \to K_{S}^{0}\pi^{+}\pi^{0})=(5.43\pm0.30_{\text{stat}}\pm 0.15_{\text{syst}})\times 10^{-3}$. \\ ( https://arxiv.org/abs/2103.15098 , 1184kb) ------------------------------------------------------------------------------ \\ arXiv:2103.15389 Date: Mon, 29 Mar 2021 07:30:43 GMT (864kb,D) Title: Measurement of the very rare $K^+\rightarrow\pi^+\nu\bar{\nu}$ decay Authors: NA62 Collaboration Categories: hep-ex \\ The NA62 experiment reports the branching ratio measurement BR$(K^+ \rightarrow \pi^+ \nu\bar{\nu}) = (10.6^{+4.0}_{-3.4} |_{\rm stat} \pm 0.9_{\rm syst}) \times 10 ^{-11}$ at 68% CL, based on the observation of 20 signal candidates with an expected background of 7.0 events from the total data sample collected at the CERN SPS during 2016-2018. This provides evidence for the very rare $K^+ \rightarrow \pi^+ \nu\bar{\nu}$ decay, observed with a significance of 3.4$\sigma$. The experiment achieves a single event sensitivity of $(0.839\pm 0.054)\times 10^{-11}$, corresponding to 10.0 events assuming the Standard Model branching ratio of $(8.4\pm1.0)\times10^{-11}$. This measurement is also used to set limits on BR($K^+ \to \pi^+ X$), where $X$ is a scalar or pseudo-scalar particle. Details are given of the analysis of the 2018 data sample, which corresponds to about 80% of the total data sample. \\ ( https://arxiv.org/abs/2103.15389 , 864kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:2007.00068 (*cross-listing*) Date: Tue, 30 Jun 2020 19:13:03 GMT (4688kb,D) Title: Neutrino decoherence from quantum gravitational stochastic perturbations Authors: Thomas Stuttard and Mikkel Jensen Categories: hep-ph gr-qc hep-ex DOI: 10.1103/PhysRevD.102.115003 \\ Neutrinos undergoing stochastic perturbations as they propagate experience decoherence, damping neutrino oscillations over distance. Such perturbations may result from fluctuations in space-time itself if gravity is a quantum force, including interactions between neutrinos and virtual black holes. In this work we model the influence of heuristic neutrino-virtual black hole interaction scenarios on neutrino propagation and evaluate the resulting signals in astrophysical and atmospheric neutrinos. We demonstrate how these effects can be represented in the framework of open quantum systems, allowing experimental constraints on such systems to be connected to quantum gravitational effects. Finally, we consider the energy-dependence of such Planck scale physics at energies observed in current neutrino experiments, and show that sensitivity to Planck scale physics well below the `natural' expectation is achievable in certain scenarios. \\ ( https://arxiv.org/abs/2007.00068 , 4688kb) ------------------------------------------------------------------------------ \\ arXiv:2103.14676 (*cross-listing*) Date: Fri, 26 Mar 2021 18:24:59 GMT (2987kb,D) Title: Quenching effects in the cumulative jet spectrum Authors: Adam Takacs and Konrad Tywoniuk Categories: hep-ph hep-ex hep-th nucl-ex nucl-th Comments: 38 pages, 12 figures \\ The steeply falling jet spectrum induces bias on the medium modifications of jet observables in heavy-ion collisions. To explore this bias, we develop a novel analytic framework to study the quenched jet spectrum, and its cumulative. We include many energy-loss-related effects, such as soft and hard medium induced emissions, broadening, elastic scattering, jet fragmentation, cone size, coherence effects, etc. We show that, different jet spectrum-based observables are connected, e.g., the nuclear modification, spectrum shift, and the quantile procedure. We present the first predictions for the nuclear modification factor and the quantile procedure with cone size dependence. As an example, we compare dijet and boson+jet events to unfold the spectrum bias effects. We improve quark-, and gluon-jet classification using arguments based on the cumulative. Besides pointing out its flexibility, we apply our framework with other energy loss models such as the hybrid weak-, strong-coupling. \\ ( https://arxiv.org/abs/2103.14676 , 2987kb) ------------------------------------------------------------------------------ \\ arXiv:2103.14691 (*cross-listing*) Date: Fri, 26 Mar 2021 18:56:26 GMT (4263kb,D) Title: Low-scale Resonant Leptogenesis in $SU(5)$ GUT with $\mathcal{T}_{13}$ Family Symmetry Authors: Chee Sheng Fong, Moinul Hossain Rahat, Shaikh Saad Categories: hep-ph hep-ex Comments: 24 pages + references, 10 figures \\ We investigate low-scale resonant leptogenesis in an $SU(5) \times \mathcal{T}_{13}$ model where a single high energy phase in the complex Tribimaximal seesaw mixing produces the yet-to-be-observed low energy Dirac and Majorana ${CP}$ phases. A fourth right-handed neutrino, required to generate viable light neutrino masses within this scenario, also turns out to be necessary for successful resonant leptogenesis where $CP$ asymmetry is produced by the same high energy phase. We derive a lower bound on the right-handed neutrino mass spectrum in the $\mathrm{ GeV}$ range, where part of the parameter space, although in tension with Big Bang Nucleosynthesis constrains, can be probed in planned high intensity experiments like DUNE. We also find the existence of a curious upper bound ($\text{TeV}$-scale) on the right-handed neutrino mass spectrum in majority of the parameter space due to significant washout of the resonant asymmetry by lighter right-handed neutrinos. \\ ( https://arxiv.org/abs/2103.14691 , 4263kb) ------------------------------------------------------------------------------ \\ arXiv:2103.14822 (*cross-listing*) Date: Sat, 27 Mar 2021 06:44:35 GMT (2751kb) Title: Gain and charge response of 20 inch MCP and dynode PMTs Authors: H.Q.

It is designed to reach an energy resolution of 3% at 1 MeV with the highest ever PMT coverage, using two types of 20 inch phototubes: MCP-PMT from NNVT and dynode-PMT from Hamamatsu. In this article, the gain and charge response of the MCP and dynode PMTs are investigated with the study of JUNO Central Detector prototype. The linearity of the MCP-PMT charge output is measured too to check the effect of a long tail on its charge spectrum. \\ ( https://arxiv.org/abs/2103.14822 , 2751kb) ------------------------------------------------------------------------------ \\ arXiv:2103.15031 (*cross-listing*) Date: Sun, 28 Mar 2021 02:05:46 GMT (734kb) Title: Quasi-two-body $B_{(s)}\to V \pi\pi$ Decays with Resonance $f_0(980)$ in PQCD Approac Authors: Lei Yang, Zhi-Tian Zou, Ying Li, Xin Liu, Cui-Hua Li Categories: hep-ph hep-ex Comments: 10 pages, 2 figures \\ Motivated by the measurements of branching fractions of the quasi-two-body decays $B^0\to K^{*0}(f_0(980)\to )\pi^+\pi^-$ and $B^0\to \rho^0(f_0(980)\to )\pi^+\pi^-$, we study the charmless $B\to V (f_0(980)\to ) \pi^+\pi^-$ decays in the perturbative QCD approach. Supposing that $f_0(980)$ is a two-quark state and mixture of $n\bar n=(u\bar u+d\bar d)/\sqrt 2$ and $s\bar s$ with the mixing angle $\theta$, we calculate the branching fractions of these decays with the new introduced $s$-wave $\pi^+\pi^-$-pair wave function. When the mixing angle $\theta$ lies in the range $[135^{\circ}, 155^{\circ}]$, the calculated branching fractions of the $B^0\to K^{*0}f_0(980)\to K^{*0}\pi^+\pi^-$ and $B^0\to \rho^0f_0(980)\to \rho^0\pi^+\pi^-$ decays are in agreement with the experimental data. The branching fractions of other decays could be measured in the current LHCb and Belle II experiments. Considering the isospin symmetry, we also estimate the branching fractions of the quasi-two-body decays $B\to Vf_0(980)\to V\pi^0\pi^0$, which are half of those the corresponding decays $B\to Vf_0(980)\to V\pi^+\pi^-$. Moreover, the direct $CP$ asymmetries of these decays are also calculated, and some of them can be tested in the current experiments. \\ ( https://arxiv.org/abs/2103.15031 , 734kb) ------------------------------------------------------------------------------ \\ arXiv:2103.15313 (*cross-listing*) Date: Mon, 29 Mar 2021 03:44:43 GMT (1301kb,D) Title: Neutrino signals of lightcone fluctuations resulting from fluctuating space-time Authors: Thomas Stuttard Categories: hep-ph gr-qc hep-ex Comments: 13 pages, 7 figure \\ One of the most common expectations of a quantum theory of gravity is that space-time is uncertain or fluctuating at microscopic scales, making it a stochastic medium for particle propagation. Particles traversing this space-time may experience fluctuations in travel times or velocities, together referred to as lightcone fluctuations, with even very small effects potentially accumulating into observable signals over large distances. In this work we present a heuristic model of lightcone fluctuations and study the resulting modifications to neutrino propagation, including neutrino decoherence and arrival time spread. We show the expected scale of such effects due to `natural' Planck scale physics and consider how they may be observed in neutrino detectors, and compare the potential of neutrinos to $\gamma$-ray astronomy. Using simulations of neutrino mass states propagating in a fluctuating environment, we determine an analytic decoherence operator in the framework of open quantum systems to quantitatively evaluate neutrino decoherence resulting from lightcone fluctuations, allowing experimental constraints on neutrino decoherence to be connected to Planck scale fluctuations in space-time and $\gamma$-ray results. \\ ( https://arxiv.org/abs/2103.15313 , 1301kb) ------------------------------------------------------------------------------ \\ arXiv:2103.15807 (*cross-listing*) Date: Mon, 29 Mar 2021 17:56:33 GMT (797kb,D) Title: Mapping the in-plane electric field inside irradiated diodes Authors: L.

The ATLAS ITk is an all-silicon detector consisting of a pixel tracker and a strip tracker. Sensors for the ITk strip tracker have been developed to withstand the high radiation environment in the ATLAS detector after the High Luminosity Upgrade of the Large Hadron Collider at CERN, which will significantly increase the rate of particle collisions and resulting particle tracks. During their operation in the ATLAS detector, sensors for the ITk strip tracker are expected to accumulate fluences up to 1.6 x 10^15 n_eq/cm^2 (including a safety factor of 1.5), which will significantly affect their performance. One characteristic of interest for highly irradiated sensors is the shape and homogeneity of the electric field inside its active area. For the results presented here, diodes with edge structures similar to full size ATLAS sensors were irradiated up to fluences comparable to those in the ATLAS ITk strip tracker and their electric fields mapped using a micro-focused X-ray beam (beam diameter 2x3 {\mu}m^2). This study shows the extension and shape of the electric field inside highly irradiated diodes over a range of applied bias voltages. Additionally, measurements of the outline of the depleted sensor areas allow a comparison of the measured leakage current for different fluences with expectations for the corresponding active areas. \\ ( https://arxiv.org/abs/2103.15807 , 797kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:2008.05342 (*cross-listing*) replaced with revised version Mon, 29 Mar 2021 13:00:33 GMT (1289kb,D) Title: Simultaneous extraction of fragmentation functions of light charged hadrons with mass corrections Authors: Maryam Soleymaninia, Muhammad Goharipour, Hamzeh Khanpour and Hubert Spiesberger Categories: hep-ph hep-ex Comments: 19 pages, 14 Figures and 4 Tables; Accepted for publication in Physical Review D \\ ( https://arxiv.org/abs/2008.05342 , 1289kb) ------------------------------------------------------------------------------ \\ arXiv:2010.00549 (*cross-listing*) replaced with revised version Sun, 28 Mar 2021 07:00:27 GMT (233kb,D) Title: Phenomenology of $\tau^- \rightarrow \pi^- \nu_{\tau} \gamma$ using LCSR Authors: Anshika Bansal, Namit Mahajan Categories: hep-ph hep-ex Comments: 22 pages, 6 figures Journal-ref: Phys.
