Search for flavour-changing neutral-current interactions of a top quark and a gluon in pp collisions at $$\sqrt{s}=13$$ TeV with the ATLAS detector

Georges Aad, +2839 more
TL;DR: In this paper , a search for the production of a single top quark via left-handed flavour-changing neutral-current (FCNC) interactions of a top particle, a gluon and an up or charm quark is presented.
Journal ArticleDOI

Erratum to: Search for supersymmetry in final states with two same-sign or three leptons and jets using 36 fb−1 of s$ \sqrt{s} $ = 13 TeV pp collision data with the ATLAS detector

TL;DR: In this article, a search for supersymmetry in final states with two same-sign or three leptons and jets using 36 fb-1 of √s = 13 TeV pp collision data with the ATLAS detector is described.
Journal ArticleDOI

Corrigendum: A search for an excited muon decaying to a muon and two jets in pp collisions at $\sqrt{s}=8\,\mathrm{TeV}$ with the ATLAS detector

Search for the Standard Model Higgs boson produced in association with top quarks and decaying into b[bar over b] in pp collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2809 more
TL;DR: In this article, a neural network is used to discriminate between signal and background events, the latter being dominated by t t ǫ+jets production, and variables calculated using a matrix element method are included as inputs to the neural network to improve discrimination.

TL;DR: In this paper, the performance of the muon reconstruction in the analysis of proton-proton collisions at the LHC was studied in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons.
