The analysis uses a data sample corresponding to a total integrated luminosity of 138 fb$^{-1}$ collected with the CMS detector at the LHC. The W bosons are identified through their leptonic decays to an electron or a muon, and a neutrino. Charm jets are taggedusing the presence of a muon or a secondary vertex inside the jet.The W+c production cross section  and  the  cross  section  ratio $R_c^{\\pm} = \\sigma({\\rm W^+ + \\bar{c}}) / \\sigma({\\rm W^- + c}) $ are measured  inclusively and differentially as functions of the transverse momentum and the pseudorapidity of the lepton originating from the W boson decay.The precision of the measurements has been improved with respect to previous studies, reaching 1% in $R_c^{\\pm}$. The measurements are compared with theoretical predictions up to next-to-next-to-leading order in perturbative quantum chromodynamics.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t1","@type":"Dataset","description":"Particle level efficiency*acceptance correction factors and cross section measurements for the four channels (W decay to muon or electron and...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t2","@type":"Dataset","description":"Parton level efficiency*acceptance correction factors and cross section measurements for the four channels (W decay to muon or electron and...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t3","@type":"Dataset","description":"Inclusive cross section predictions at QCD NLO accuracy from MCFM using different PDF sets","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t4","@type":"Dataset","description":"Inclusive cross section predictions up to QCD NNLO accuracy using the NNPDF3.1 PDF set","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t5","@type":"Dataset","description":"Measured production cross sections ratio $\\sigma(W^+ + \\overline{c})$ / $\\sigma(W^- + c)$","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t6","@type":"Dataset","description":"Predictions for the cross sections ratio $\\sigma(W^+ + \\overline{c})$ / $\\sigma(W^- + c)$ at QCD NLO accuracy from MCFM using...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t7","@type":"Dataset","description":"Predictions for the cross sections ratio $\\sigma(W^+ + \\overline{c})$ / $\\sigma(W^- + c)$ up to QCD NNLO accuracy using the...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t8","@type":"Dataset","description":"Measured diferential cross sections $\\sigma(W^- + c) + \\sigma(W^+ + \\overline{c})$ as a function of the absolute value of the...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t9","@type":"Dataset","description":"Measured diferential cross sections as a function of the transverse momentum of the lepton from the W decay, unfolded to...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t10","@type":"Dataset","description":"Measured diferential cross sections $\\sigma(W^- + c) + \\sigma(W^+ + \\overline{c})$ as a function of the absolute value of the...","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t11","@type":"Dataset","description":"Measured diferential cross sections as a function of the transverse momentum of the lepton from the W decay, unfolded to...","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t12","@type":"Dataset","description":"Measured diferential cross sections ratio $R=\\sigma(W^+ + \\overline{c}) / \\sigma(W^- + c)$ as a function of the absolute value of...","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.141611.v1/t13","@type":"Dataset","description":"Measured diferential cross sections ratio $R=\\sigma(W^+ + \\overline{c}) / \\sigma(W^- + c)$ as a function of the transverse momentum of...","name":"Table 13"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2685711?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/141611"}],"inLanguage":"en","name":"Measurement of the production cross section for a W boson in association with a charm quark in proton-proton collisions at $\\sqrt{s}$ = 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2685711?version=1","version":1}
