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

- Computing and software for big science

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.

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

Georges Aad, +2847 more

- 18 Jun 2015

- Journal of Instrumentation

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.

Search for a light charged Higgs boson in the decay channel H+ -> c(s)over-bar in t(t)over-bar events using pp collisions at root s=7 TeV with the ATLAS detector

Georges Aad, +2880 more

- 06 Jun 2013

- European Physical Journal C

TL;DR: In this article, a search for a charged Higgs boson (H+) in t (t) over bar decays is presented, where one of the top quarks decays via t -> H(+)b, followed by H+ -> two jets (c (s) over bars).

Search for direct chargino production in anomaly-mediated supersymmetry breaking models based on a disappearing-track signature in pp collisions at √s=7TeV with the ATLAS detector

Georges Aad, +2945 more

- 18 Jan 2013

- Journal of High Energy Physics

TL;DR: In this paper, a search for direct chargino production in anomaly-mediated supersymmetry breaking scenarios is performed in p p collisions at root s = 7 TeV using 4.7 fb(-1) of data collected with the ATLAS experiment at the LHC.

Search for the standard model Higgs boson in the diphoton decay channel with 4.9fb -1 of pp collision data at √s=7TeV with atlas

Georges Aad, +3100 more

- 13 Mar 2012

- Physical Review Letters

TL;DR: In this article, a search for the standard model Higgs boson is performed in the diphoton decay channel, and the largest excess with respect to the background-only hypothesis is observed at 126.5 GeV, with a local significance of 2.8 standard deviations.
