Search for supersymmetry in events with three leptons and missing transverse momentum in √s=7TeV pp collisions with the ATLAS detector

Georges Aad, +2914 more
- 29 Jun 2012 - 
TL;DR: A search for the weak production of charginos and neutralinos decaying to a final state with three leptons (electrons or muons) and missing transverse momentum is presented and observations are consistent with standard model expectations in two signal regions that are either depleted or enriched in Z-boson decays.
Journal ArticleDOI

Performance of a Low Noise Front-end ASIC for Si/CdTe Detectors in Compton Gamma-ray Telescope

H. Tajima, +13 more
- 01 Apr 2004 - 
TL;DR: The VA32TA as discussed by the authors achieves an energy resolution of 1.3 keV (FWHM) for 60 keV and 122 keV at 0 degree C with a DSSD and 1.7 keV with a CdTe detector.
Journal ArticleDOI

A search for tt̄ resonances in lepton+jets events with highly boosted top quarks collected in pp collisions at √s = 7TeV with the ATLAS detector

Georges Aad, +2914 more
- 13 Sep 2012 - 
TL;DR: In this paper, a search for resonant production of high-mass top-quark pairs is performed on 2.05 fb(-1) of proton-proton collisions at root s = 7 TeV collected in 2011 with the ATLAS experiment at the Large Hadron Collider.
Journal ArticleDOI

Search for Higgs and Z boson decays to J/ψγ and ϒ(nS)γ with the ATLAS detector

Georges Aad, +2815 more
- 26 Mar 2015 - 
TL;DR: In this article, a search for the decays of the Higgs and Z bosons to J/psi gamma and Upsilon(nS)gamma (n = 1,2,3) is performed with pp collision data samples corresponding to integrated luminosities of up to 20.3 fb(-1) collected at root s = 8 TeV with the ATLAS detector at the CERN Large Hadron Collider.
Journal ArticleDOI

Observation of Centrality-Dependent Acoplanarity for Muon Pairs Produced via Two-Photon Scattering in Pb+Pb Collisions at sNN =5.02 TeV with the ATLAS Detector

Morad Aaboud, +2927 more
- 19 Nov 2018 - 
TL;DR: This Letter presents a measurement of γγ→μ+}μ^{-} production in Pb+Pb collisions recorded by the ATLAS detector at the Large Hadron Collider at sqrt[s_{NN}]=5.02 TeV with an integrated luminosity of 0.49‬nb^{-1}.
