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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t1","@type":"Dataset","description":"Measured integrated cross sections of the production of a W boson with a single c-jet, a D meson or a...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t2","@type":"Dataset","description":"Measured integrated cross section ratios of the production of W+ and W- bosons associated with a single c-jet, a D...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t3","@type":"Dataset","description":"Measured differential cross sections as function of the lepton pseudo-rapidity of the production of a W boson with a single...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t4","@type":"Dataset","description":"Measured differential cross sections as function of the lepton pseudo-rapidity of the production of a W boson with a D...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t5","@type":"Dataset","description":"Measured cross section ratios of the production of a W boson with a D meson or a D* meson and...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t6","@type":"Dataset","description":"Measured differential cross section ratios of the production of a W boson with a D meson or a D* meson...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t7","@type":"Dataset","description":"Measured integrated cross sections of the production of a W boson in association with a single c-jet and exactly zero...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t8","@type":"Dataset","description":"Measured integrated cross sections ratio of the production of a W+ and W- bosons in association with a single c-jet...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t9","@type":"Dataset","description":"Measured integrated cross sections of the production of a W boson in association with a single c-jet decaying into a...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t10","@type":"Dataset","description":"Correlation matrix corresponding to the total uncertainties of measured integrated cross sections of the production of a W boson with...","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.63197.v1/t11","@type":"Dataset","description":"Systematic uncertainties after the averaging procedure of the inclusive cross sections in different channels.
