Measurement of dijet production with a veto on additional central jet activity in pp collisions at √s = 7 TeV using the ATLAS detector
(2011)
A measurement of jet activity in the rapidity interval bounded by a dijet system is presented. Events are vetoed if a jet with transverse momentum greater than 20GeV is found between the two boundary jets. The fraction of ...
Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector
(2011)
Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb−1 recorded at the ...
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 ...
Search for high-mass states with one lepton plus missing transverse momentum in proton–proton collisions at √s = 7 TeV with the ATLAS detector
(2011)
The ATLAS detector is used to search for high-mass states, such as heavy charged gauge bosons (W′,W⁎), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp ...
Search for a heavy neutral particle decaying into an electron and a muon using 1 fb−1 of ATLAS data
(2011)
A search is presented for a high mass neutral particle that decays directly to the e±μ∓ final state. The data sample was recorded by the ATLAS detector in √ s = 7 TeV pp collisions at the LHC from March to June 2011 and ...
Measurement of the W charge asymmetry in the W → μν decay mode in pp collisions at √s = 7 TeV with the ATLAS detector ✩
(2011)
This Letter reports a measurement of the muon charge asymmetry from W bosons produced in proton–proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS experiment at the LHC. The asymmetry is measured in the ...
Measurement of W γ and Zγ production in proton-proton collisions at √s = 7 TeV with the ATLAS detector
(2011)
We present studies of W and Z bosons with associated high energy photons produced in pp collisions at √s = 7TeV. The analysis uses 35 pb γ + X) event candidates are selected. The kinematic distributions of the leptons and ...
Measurements of underlying-event properties using neutral and charged particles in pp collisions at √s = 900 GeV and √s = 7 TeV with the ATLAS detector at the LHC
(2011)
We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters.Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV.Events were ...
Search for stable hadronising squarks and gluinos with the ATLAS experiment at the LHC ✩
(2011)
Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for ...
Studies of the performance of the ATLAS detector using cosmic-ray muons
(2011)
Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector. Cosmic-ray muons can penetrate to the ...
