Search for top and bottom squarks from gluino pair production in final states with missing transverse energy and at least three b-jets with the ATLAS detector
(2012)
This letter reports the results of a search for top and bottom squarks from gluino pair production in 4.7 fb−1of pp collisions at √s = 7 TeV using the ATLAS detector at the LHC. The search is performed in events with large ...
Measurement of the top quark mass with the template method in the tt ¯→ lepton + jets channel using ATLAS data
(2012)
The top quark mass has been measured using the
template method in the tt
¯→ lepton + jets channel based on
data recorded in 2011 with the ATLAS detector at the LHC.
The data were taken at a proton-proton centre-of-mass ...
ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at √s = 7 TeV
(2013)
Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy √s = 7TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity ...
Evidence for the associated production of a √ W boson and a top quark in ATLAS at s = 7 TeV ✩
(2012)
This Letter presents evidence for the associated production of a W boson and a top quark using 2.05 fb−1 of pp collision data at s=7TeV accumulated with the ATLAS detector at the LHC. The analysis is based on the selection ...
Search for the Standard Model Higgs boson in the H → W W () → νν decay mode with 4.7 fb−1 of ATLAS data at √s = 7 TeV ✩

A search for the Standard Model Higgs boson in the H→WW(⋆)→ℓνℓν (ℓ=e,μ) decay mode is presented. The search is performed using proton–proton collision data corresponding to an integrated luminosity of 4.7 fb−1 at a ...
Measurement of the azimuthal anisotropy for charged particle production in √sN N = 2.76 TeV lead-lead collisions with the ATLAS detector
(2012)
Differential measurements of charged particle azimuthal anisotropy are presented for lead-lead collisions at √sNN = 2.76 TeV with the ATLAS detector at the LHC, based on an integrated luminosity of approximately 8 μb− 1. ...
Search for anomaly-mediated supersymmetry breaking with the ATLAS detector based on a disappearing-track signature in pp collisions at √s = 7 TeV
(2012)
In models of anomaly-mediated supersymmetry breaking (AMSB), the lightest chargino is predicted to have a lifetime long enough to be detected in collider experiments. This letter explores AMSB scenarios in pp collisions ...
Measurement of the jet fragmentation function and transverse profile in proton–proton collisions at a center-of-mass energy of 7 TeV with the ATLAS detector
(2011)
The jet fragmentation function and transverse profile for jets with 25 GeV< pTjet < 500 GeV and |ηjet| < 1.2 produced in proton–proton collisions with a center-ofmass energy of 7 TeV are presented. The measurement is ...
ATLAS search for a heavy gauge boson decaying to a charged lepton and a neutrino in pp collisions at √s = 7 TeV
(2012)
The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (Wʹ), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of ...
Search for a heavy top-quark partner in final states with two leptons with the ATLAS detector at the LHC
(2012)
The results of a search for direct pair production of heavy top-quark partners in 4.7 fb–1 of integrated luminosity from pp collisions at √s = 7 TeV collected by the ATLAS detector at the LHC are reported. Heavy top-quark ...
