Measurement of the c-jet mistagging efficiency in $$t\bar{t}$$ events using pp collision data at $$\sqrt{s}=13$$ $$\text {TeV}$$ collected with the ATLAS detector

Georges Aad, +2842 more
TL;DR: In this paper , a technique is presented to measure the efficiency with which c-jets are mistagged as b-Jets (mistagging efficiency) using $$t\bar{t}$$.
Journal ArticleDOI

A search for the decays of stopped long-lived particles at √s = 13 TeV with the ATLAS detector

Georges Aad, +2948 more
- 23 Jul 2021 - 
TL;DR: In this paper, a search for long-lived particles, which have come to rest within the ATLAS detector, is presented, where the results of this search are used to derive lower limits on the mass of gluino R-hadrons, assuming a branching fraction B(g~→qq¯χ10) = 100%, with masses of up to 1.4 TeV excluded for gluinos lifetimes of 10−5 to 103 s.
Journal ArticleDOI

Search for Dark Matter Produced in Association with a Dark Higgs Boson Decaying into W^{±}W^{∓} or ZZ in Fully Hadronic Final States from sqrt[s]=13 TeV pp Collisions Recorded with the ATLAS Detector.

- 26 Mar 2021 - 
TL;DR: An uncharted signature of dark matter particles produced in association with VV=W^{±}W^{∓} or ZZ pairs from a decay of a dark Higgs boson s is searched for using 139 fb^{-1} of pp collisions recorded by the ATLAS detector at a center-of-mass energy of 13 TeV.
Journal ArticleDOI

Erratum to: Search for diboson resonances in hadronic final states in 139 fb −1 of pp collisions at s = 13 TeV with the ATLAS detector (Journal of High Energy Physics, (2019), 2019, 9, (91), 10.1007/JHEP09(2019)091)

TL;DR: A mistake was identified for the paper [1] in the treatment of the radion cross-sections, which resulted in multiple changes.
Journal ArticleDOI

Measurements of the Higgs boson inclusive and differential fiducial cross-sections in the diphoton decay channel with pp collisions at $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

TL;DR: In this article , a measurement of the cross-sections for the production of the Higgs boson decaying into two photons is performed using $139~\text{fb}^{-1}$ of proton-proton collision data recorded at 13$ TeV by the ATLAS experiment at the Large Hadron Collider.
