Measurement of soft-drop jet observables in $pp$ collisions with the ATLAS detector at $\sqrt {s}$ =13 TeV

G. Aad, Brad Abbott, H. Abreu, Francisco Anuar Arduh et autres

Jet substructure quantities are measured using jets groomed with the soft-drop grooming procedure in dijet events from 32.9 fb-1 of pp collisions collected with the ATLAS detector at s=13 TeV. These observables are sensitive to a wide range of QCD phenomena. Some …

G. Aad, Brad Abbott, Henso Abreu, Rodrigo Araujo Pereira et autres

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy …

Measurement of azimuthal anisotropy of muons from charm and bottom hadrons in Pb+Pb collisions at $\sqrt{s_{NN}} =$ 5.02 TeV with the ATLAS detector

Georges Aad, Brad Abbott, Henso Abreu, C. Arcangeletti et autres

Azimuthal anisotropies of muons from charm and bottom hadron decays are measured in Pb+Pb collisions at $\sqrt{s_{NN}}=$ 5.02 TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2018 with integrated luminosities of 0.5 ${nb}^{-1}$ …

Measurement of angular and momentum distributions of charged particles within and around jets in Pb+Pb and pp collisions at sNN=5.02 TeV with the ATLAS detector

G. Aad, B. Abbott, D. C. Abbott, A. Abed Abud et autres

Studies of the fragmentation of jets into charged particles in heavy-ion collisions can provide information about the mechanism of jet quenching by the hot and dense QCD matter created in such collisions, the quark-gluon plasma. This paper presents a measurement of the …

Resolution of the ATLAS muon spectrometer monitored drift tubes in LHC Run 2

Georges Aad, Abbott, Brad, D. C. Abbott, Abdinov, Ovsat et autres

The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers.Optimal resolution is achieved with a dedicated calibration program that addresses the specific operating conditions of the 354 …
