title = "Measurement of the production of a W boson in association with a charmed hadron in pp collisions at √s = 13 TeV with the ATLAS detector",
abstract = "The production of a W boson in association with a single charm quark is studied using 140 fb-1 of √s = 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. The charm quark is tagged by the presence of a charmed hadron reconstructed with a secondary-vertex fit. The W boson is reconstructed from the decay to either an electron or a muon and the missing transverse momentum present in the event. The charmed mesons reconstructed are D+ → K-π +π + and D*+ → D0π + → ( K-π+ ) π+ and the charge conjugate decays in the fiducial regions where pT ( e , μ ) > 30 GeV , | η (e , μ) | < 2.5 , pT ( D(*) ) > 8 GeV , and | η (D(*) ) | < 2.2 . The integrated and normalized differential cross sections as a function of the pseudorapidity of the lepton from the W boson decay, and of the transverse momentum of the charmed hadron, are extracted from the data using a profile likelihood fit. The measured total fiducial cross sections are σfid OS-SS (W- + D+) = 50.2 ± 0.2 (stat)-2.3 +2.4 (syst) pb , σfid OS-SS (W+ + D-) = 48.5 ± 0.2 (stat) -2.2 +2.3 (syst) pb , σ fid OS-SS (W- + D*+ ) = 51.1 ± 0.4 (stat) -1.8 +1.9 (syst) pb , and σ fid OS-SS ( W+ + D*- ) = 50.0 ± 0.4 (stat) -1.8 +1.9 (syst) pb . Results are compared with the predictions of next-to-leading-order quantum chromodynamics calculations performed using state-of-the-art parton distribution functions. Additionally, the ratio of charm to anticharm production cross sections is studied to probe the s-s¯ quark asymmetry. The ratio is found to be Rc± = 0.971 ± 0.006 (stat) ± 0.011 (syst) . The ratio and cross-section measurements are consistent with the predictions obtained with parton distribution function sets that have a symmetric s-s¯ sea, indicating that any s-s¯ asymmetry in the Bjorken- x region relevant for this measurement is small.",
