Journal ArticleDOI

Search for trilepton resonances from chargino and neutralino pair production in s =13 TeV pp collisions with the ATLAS detector

Georges Aad, +2969 more
- 07 Jun 2021 - 
TL;DR: In this article, a search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W-, $Z-, or Higgs boson.
Journal ArticleDOI

Determination of the parton distribution functions of the proton using diverse ATLAS data from pp collisions at $$\sqrt{s} = 7$$, 8 and 13 TeV

Georges Aad, +2789 more
- 01 May 2022 - 
TL;DR: In this paper , a new set of proton parton distribution functions using diverse measurements in $pp$ collisions at $\sqrt{s} = 7, 8 and 13 TeV, performed by the ATLAS experiment at the Large Hadron Collider, together with deep inelastic scattering data from $ep$ collisions from HERA collider.
Journal ArticleDOI

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

Search for top squarks in events with a Higgs or Z boson using 139 fb−1 of pp collision data at √s=13 TeV with the ATLAS detector

Georges Aad, +2964 more
- 23 Nov 2020 - 
TL;DR: In this paper, a search for direct top-squark pair production in events with missing transverse momentum plus either a pair of jets consistent with Standard Model Higgs boson decay into b-quar is presented.

Measurement of the azimuthal anisotropy for charged particle production in √s[subscript NN]=2.76 TeV lead-lead collisions with the ATLAS detector

Georges Aad, +3025 more
TL;DR: A Fourier analysis of the charged particle pair distribution in relative azimuthal angle (φ = φ a − φ b) is performed to extract the coefficients v n,n = =cos nnφ.
