Modelling $Z\rightarrow\tau\tau$ processes in ATLAS with $\tau$-embedded $Z\rightarrow\mu\mu$ data

Georges Aad, +2847 more
- 18 Jun 2015 - 
TL;DR: In this article, the authors describe the concept, technical realisation and validation of a largely data-driven method to model events with Z→ττ decays, which is particularly relevant for Higgs boson searches and analyses in ττ final states, where Zarrowτ τ decays constitute a large irreducible background that cannot be obtained directly from data control samples.
Journal ArticleDOI

AtlFast3: The Next Generation of Fast Simulation in ATLAS

Georges Aad, +2845 more
- 11 Mar 2022 - 
TL;DR: The ATLAS experiment at the Large Hadron Collider has a broad physics programme ranging from precision measurements to direct searches for new particles and new interactions, requiring ever larger and ever more accurate datasets of simulated Monte Carlo events as discussed by the authors .
Journal ArticleDOI

Measurement of the nuclear modification factor for muons from charm and bottom hadrons in Pb+Pb collisions at 5.02 TeV with the ATLAS detector

Georges Aad, +2839 more
- 01 Apr 2022 - 
TL;DR: In this article , a measurement of the muons from semileptonic decays of charm and bottom hadrons produced in Pb+Pb and $pp$ collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV with the ATLAS detector at the Large Hadron Collider is presented.
Journal ArticleDOI

Emulating the impact of additional proton–proton interactions in the ATLAS simulation by presampling sets of inelastic Monte Carlo events

Georges Aad, +2784 more
- 27 Jan 2022 - 
TL;DR: In this paper , a new method to account for these additional interactions in the simulation chain is described, instead of sampling the inelastic interactions and adding their energy deposits to a hard-scatter interaction one-by-one, the interactions are presampled, independent of the hard scatter, and stored as combined events.
Journal ArticleDOI

Search for long-lived charginos based on a disappearing-track signature using 136 fb$$^{-1}$$ of pp collisions at $$\sqrt{s}$$ = 13 TeV with the ATLAS detector

Georges Aad, +2819 more
TL;DR: In this paper , a search for long-lived charginos produced either directly or in the cascade decay of heavy prompt gluino states is presented, based on proton-proton collision data collected at a centre-of-mass energy of 13 TeV between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 136 fb$^{-1}$.
