Measurement of the associated production of a Higgs boson decaying into b-quarks with a vector boson at high transverse momentum in pp collisions at s=13 TeV with the ATLAS detector

Georges Aad, +2951 more
- 10 May 2021 - 
TL;DR: In this article, the associated production of a Higgs boson decaying into b quark pairs with a W or Z gauge boson, decaying into leptons, are measured in two exclusive vector boson transverse momentum regions, 250-400 GeV and above 400 GeV, and interpreted as constraints on anomalous couplings in the framework of a Standard Model effective field theory.

Search for anomalous production of prompt like-sign muon pairs and constraints on physics beyond the standard model with the ATLAS detector

Georges Aad, +3042 more
- 17 Feb 2012 - 
TL;DR: In this paper, an inclusive search for anomalous production of two prompt, isolated muons with the same electric charge was performed in a data sample corresponding to 1.6 fb(-1) of integr...

Observation of top-quark pair production in association with a photon and measurement of the t t ¯ γ production cross section in pp collisions at √s =7 TeV using the ATLAS detector

Georges Aad, +2899 more
- 28 Apr 2015 - 
TL;DR: In this paper, a search is performed for top-quark pairs (t (t) over bar) produced together with a photon (gamma) with transverse energy greater than 20 GeV using a sample of t (t)-over-bar candidate events in final states with jets, missing transverse momentum, and one isolated electron or muon.

Search for a scalar partner of the top quark in the all-hadronic tt‾ plus missing transverse momentum final state at √s=13 TeV with the ATLAS detector

Georges Aad, +2949 more
- 01 Aug 2020 - 
TL;DR: A search for direct pair production of scalar partners of the top quark (top squarks or scalar third-generation up-type leptoquarks) in the all-hadronic t (t) over bar plus missing transverse momen was conducted in this paper.

Measurements of Wγ and Zγ production in pp collisions at √s=7 TeV with the ATLAS detector at the LHC

Georges Aad, +2923 more
TL;DR: The integrated and differential cross sections for the production of a W or Z boson in association with a high-energy photon are measured using pp collisions atfined as the difference between N obs Z(cid:3) and the total number of expected background events.
