Measurement of KS0 and Λ production in tt¯ dileptonic events in pp collisions at √s= 7 TeV with the ATLAS detector

Georges Aad, +2973 more
- 17 Dec 2019 - 
TL;DR: In this paper, measurements of K-S and Lambda production in tt final states have been performed based on a data sample with integrated luminosity of 4.6 fb(-1) from proton-proton collisions at a c...

Performance of the ATLAS Level-1 topological trigger in Run 2

Georges Aad, +2883 more
TL;DR: The ATLAS Level-1 topological trigger as mentioned in this paper uses Field Programmable Gate Array processors to select interesting events by placing kinematic and angular requirements on electromagnetic clusters, jets, $\tau$-leptons, muons and the total energy.

Emulating the impact of additional proton-proton interactions in the ATLAS simulation by pre-sampling sets of inelastic Monte Carlo events

Georges Aad, +2848 more
TL;DR: In this article, 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

Combination of searches for invisible decays of the Higgs boson using 139 fb−1 of proton-proton collision data at s=13 TeV collected with the ATLAS experiment

Georges Aad, +2770 more
- 01 May 2023 - 
TL;DR: In this paper , a statistical combination of searches for H $\rightarrow$ invisible decays where multiple production modes of the Standard Model Higgs boson are considered was performed with the ATLAS detector using 139 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 13$ TeV at the LHC.

Detector and Beamline Simulation for Next-Generation High Energy Physics Experiments

Sw. Banerjee, +33 more
TL;DR: In this article , the authors describe the state, current and future needs of high energy physics detector and beamline simulations and related challenges, and propose a number of possible ways to address them.
