High energy particle physics faces huge challenge in software and
computing in the coming decade. At the LHC ALICE and LHCb will make
major upgrades for Run 3, requiring much improved software, while the
challenges faced by ATLAS and CMS for High Luminosity LHC imply that
software and computing must improve by around x10 beyond technology
evolution alone to fit into the anticipated resources....
The reconstruction of trajectories from charged particles in the ATLAS Inner Detector is the most single CPU intensive part of the event reconstruction. The currently implemented combinatorial approach with track following will suffer strongly from the increasing event complexity foreseen with the future high luminosity programs in high energy physics. On the other hand, machine learning (ML)...
The Standard Model (SM) of particle physics is currently the best theory for describing elementary particles and their interactions, but there are several problems and open questions related to it. For instance it does not incorporate gravity, and it does not explain dark matter, hence there is a need for new fundamental theories of nature beyond the current theory. A theory that addresses...
A search is conducted for new resonant and nonresonant high-mass phenomena in di-electron and dimuon final states. The search uses 36.1 fb−1 of proton-proton collision data, collected at √s = 13 TeV by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the Standard Model prediction is observed. Upper limits at 95% credibility level are set on the cross-section...
A search for the electroweak production of charginos, neutralinos and sleptons decaying to final states involving two or three electrons or muons is presented. The analysis is based on 36.1 fb^{-1} of √s=13 TeV proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider. No significant deviations from the Standard Model expectation are observed and results are...
The results of a search for new heavy W' bosons decaying to an electron or muon and a neutrino using proton-proton collision data at a centre-of-mass energy of 13 TeV are presented. The dataset was collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1 fb-1. As no excess of events above the Standard Model predictions...
From the perspective of indirect detection, gamma rays would make excellent messengers of a potential dark matter signal. Not only do they point towards their sources, their energy spectrum may also carry smoking-gun features that allow to pinpoint the particle nature of dark matter. In particular, Bringmann et al. (2017) recently highlighted that excited Standard Model meson states, resulting...
