Search for contact interactions and large extra dimensions in dilepton events from pp collisions at √s=7 TeV with the ATLAS detector

Georges Aad, +2899 more
- 04 Jan 2013 - 
TL;DR: In this paper, a search for nonresonant new phenomena, originating from either contact interactions or large extra spatial dimensions, has been carried out using events with two isolated electrons or muons.
Journal ArticleDOI

Search for heavy particles decaying into a top-quark pair in the fully hadronic final state in pp collisions at √s = 13 TeV with the ATLAS detector

Morad Aaboud, +2987 more
- 14 May 2019 - 
TL;DR: A search for new particles decaying into a pair of top quarks is performed using proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energ...
Journal ArticleDOI

Measurement of the production cross-section of a single top quark in association with a Z boson in proton–proton collisions at 13 TeV with the ATLAS detector

Morad Aaboud, +2909 more
- 10 May 2018 - 
TL;DR: In this paper, a neural network was used to improve the background rejection and extract the signal of top quark production in the collision data collected by the ATLAS experiment at the LHC in 2015 and 2016.
Journal ArticleDOI

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum with ATLAS using √s=13 TeV proton-proton collisions

Georges Aad, +2844 more
- 10 Jun 2016 - 
TL;DR: In this paper, a search for new phenomena, such as supersymmetric particle production, that could be observed in high-energy proton-proton collisions was conducted, where events with large numbers of jets, together with missing transverse momentum from unobserved particles, were selected.

Search for nonpointing and delayed photons in the diphoton and missing transverse momentum final state in 8 TeV pp collisions at the LHC using the ATLAS detector

Georges Aad, +2873 more
TL;DR: In this paper, a search was performed using the full 20.3 fb(-1) data sample of 8 TeV proton-proton collisions collected in 2012 with the ATLAS detector at the LHC, for photons originating from a displaced vertex due to the decay of a neutral long-lived particle into a photon and an invisible particle.
