Title: Measurement of the production of a $W$ boson in association with a charm quark in $p p$ collisions at $\sqrt{s} =$ 7 TeV with the ATLAS detector

Abstract

CERN-LHC. The production of a W boson in association with a single charm quark is studied using 4.6 fb^-1 of pp collision data at sqrt(s) = 7 TeV collected in 2011 with the ATLAS detector at the Large Hadron Collider. In events in which a W boson decays to an electron or muon, the charm quark is tagged either by its semileptonic decay to a muon or by the presence of a charmed meson. The integrated and differential cross sections as a function of the pseudorapidity of the lepton from the W-boson decay are measured. Results are compared to the predictions of next-to-leading-order QCD calculations obtained from various parton distribution function parameterisations. The ratio of the strange-to-down sea quark distributions is determined to be 0.96 +0.26,-0.30 at Q^2 = 1.9 GeV^2 which supports the hypothesis of an SU(3) symmetric composition of the light quark sea. Additionally, the cross-section ratio sigma(W^+ + cbar)/sigma(W^- + c) is compared to the predictions obtained using parton distribution function parameterisations with different assumptions on the s-sbar asymmetry.

Measurement of the production cross section of prompt $J / ψ$ mesons in association with a $W^{\pm}$ boson in $p p$ collisions at $\sqrt{s} =$ 7 TeV with the ATLAS detector

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. The process P P --> W J/PSI X provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons. Using the 2011 ATLAS dataset of 4.5 fb^-1 of sqrt(s) = 7 TeV pp collisions at the LHC, the first observation is made of the production of W + prompt J/psi events in hadronic collisions, using W --> MU NU and J/PSI --> MU MU. A yield of 27.4 +7.5,-6.5 W + prompt J/psi events is observed, with a statistical significance of 5.1 sigma. The productionmore »« less

CERN-LHC. Measurement of the inclusive W+jets cross section in proton-proton collisions at centre-of-mass enrgy 7 TeV. The data, collected from March to August 2010 have an integrated luminosity of 1.3 pb-1, and have been corrected for all known detector effects and are quoted within limited and well defined ranges of jet and lepton kinematics. Jets were reconstructed using the anti-kT algoithm with radius parameter R = 0.4. The lepton energy is defined as the energy of the lepton after radiation plus the energy of all radiated photons within DeltaR=0.1 around the lepton.
