Measurement of exclusive γγ→ℓ+ℓ− production in proton–proton collisions at √s=7 TeV with the ATLAS detector
This Letter reports a measurement of the exclusive γγ→ℓ+ℓ− (ℓ=e, μ) cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV by the ATLAS experiment at the LHC, based on an integrated luminosity of 4.6 ...
Measurement of differential J/ψ production cross sections and forward-backward ratios in p + Pb collisions with the ATLAS detector
Measurements of differential cross sections for J/ψ production in p + Pb collisions at (√SNN at the CERN Large Hadron Collider with the ATLAS detector are presented. The data set used corresponds to an integrated luminosity ...
Search for the associated production of the Higgs boson with a top quark pair in multilepton final states with the ATLAS detector
A search for the associated production of the Higgs boson with a top quark pair is performed in multilepton final states using 20.3 fb−1 of proton–proton collision data recorded by the ATLAS experiment at s=8 TeV at the ...
Z boson production in p+Pb collisions at s NN =5.02 TeV measured with the ATLAS detector
The ATLAS Collaboration measures the inclusive production of Z bosons via their decays into electron and muon pairs in p+Pb collisions at sNN=5.02TeV at the Large Hadron Collider. The measurements are made using data ...
Measurement of the branching ratio Γ(Λb 0→ψ(2S)Λ0)/Γ(Λb 0→J/ψΛ0) with the ATLAS detector
