Search for the Higgs Boson in the H→WW(*)→l+νl–ν¯ decay channel in pp collisions at s=7TeV with the ATLAS detector

Georges Aad, +3043 more

Abstract: A search for the Higgs boson has been performed in the H -> WW(*()) -> l+vl-(v) over bar channel (l = e/mu) with an integrated luminosity of 2.05 fb(-1) of pp collisions at root s = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. No significant excess of events over the expected background is observed and limits on the Higgs boson production cross section are derived for a Higgs boson mass in the range 110 GeV< m(H) < 300 GeV. The observations exclude the presence of a standard model Higgs boson with a mass 145 < m(H) < 206 GeV at 95% confidence level.

Search for supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 20 fb-1 of s \sqrt{s} = 8 TeV proton-proton collision data with the ATLAS detector

Georges Aad, +2922 more
- 18 Sep 2014 - 
TL;DR: In this paper, a search for supersymmetry in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3 fb(-1) of proton-proton collision data at root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Collider.

A search for prompt lepton-jets in pp collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2899 more
- 09 Feb 2016 - 
TL;DR: In this paper, a search is presented for a new light boson with a mass of about 1 GeV and decaying promptly to jets of collimated electrons and/or muons (lepton-jets).
Journal ArticleDOI

Studies of the performance of the ATLAS detector using cosmic-ray muons

Georges Aad, +2531 more
- 29 Mar 2011 - 
TL;DR: In this paper, the results of performance studies related to combined tracking, lepton identification and the reconstruction of jets and missing transverse energy are compared to expectations based on a cosmic-ray event generator and a full simulation of the detector response.
Journal ArticleDOI

Search for pair production of heavy vectorlike quarks decaying into hadronic final states in pp collisions at s =13 TeV with the ATLAS detector

Morad Aaboud, +2914 more
- 01 Nov 2018 - 
TL;DR: In this article, a search for the pair production of heavy vector-like quarks, TT¯ or BB¯, that decay into final states with jets and no reconstructed leptons is presented.
