The charm quark is tagged by a charmed hadron, reconstructed with a secondary-vertex fit. The $W$ boson is reconstructed from an electron/muon decay and the missing transverse momentum. The mesons reconstructed are $D^{\\pm} \\to K^\\mp \\pi^\\pm \\pi^\\pm$ and $D^{*\\pm} \\to D^{0} \\pi^\\pm \\to (K^\\mp \\pi^\\pm) \\pi^\\pm$, where $p_{\\text{T}}(e, \\mu) > 30\\,\\mathrm{GeV}$, $|\\eta(e, \\mu)| < 2.5$, $p_{\\text{T}}(D) > 8\\,\\mathrm{GeV}$, and $|\\eta(D)| < 2.2$. 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 meson, are extracted from the data using a profile likelihood fit. The measured fiducial cross-sections are $\\sigma^{\\mathrm{OS-SS}}_{\\mathrm{fid}}(W^{-}{+}D^{+}) = 50.2\\pm0.2\\,\\mathrm{(stat.)}\\,^{+2.4}_{-2.3}\\,\\mathrm{(syst.)}\\,\\mathrm{pb}$, $\\sigma^{\\mathrm{OS-SS}}_{\\mathrm{fid}}(W^{+}{+}D^{-}) = 48.5\\pm0.2\\,\\mathrm{(stat.)}\\,^{+2.3}_{-2.2}\\,\\mathrm{(syst.)}\\,\\mathrm{pb}$, $\\sigma^{\\mathrm{OS-SS}}_{\\mathrm{fid}}(W^{-}{+}D^{*+}) = 51.1\\pm0.4\\,\\mathrm{(stat.)}\\,^{+1.9}_{-1.8}\\,\\mathrm{(syst.)}\\,\\mathrm{pb}$, and $\\sigma^{\\mathrm{OS-SS}}_{\\mathrm{fid}}(W^{+}{+}D^{*-}) = 50.0\\pm0.4\\,\\mathrm{(stat.)}\\,^{+1.9}_{-1.8}\\,\\mathrm{(syst.)}\\,\\mathrm{pb}$. Results are compared with the predictions of next-to-leading-order quantum chromodynamics calculations performed using state-of-the-art parton distribution functions. The ratio of charm to anti-charm production cross-sections is studied to probe the $s$-$\\bar{s}$ quark asymmetry and is found to be $R_c^\\pm = 0.971\\pm0.006\\,\\mathrm{(stat.)}\\pm0.011\\,\\mathrm{(syst.)}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.136060.v1/t1","@type":"Dataset","description":"Measured fiducial cross-sections times the single-lepton-flavor W boson branching ratio.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.136060.v1/t2","@type":"Dataset","description":"Measured cross section ratios for the W+D production.
