Abstract
Measurements are presented of associated production of a W boson and a charm quark (W + c) in protonproton collisions at a center-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 35.7 fb -1 collected by the CMS experiment at the CERN LHC. The W bosons are identified by their decay into a muon and a neutrino. The charm quarks are tagged via the full reconstruction of D * (2010) mesons that decay via D * (2010) D 0 + K + + . A cross section is measured in the fiducial region defined by the muon transverse momentum p T > 26 GeV, muon pseudorapidity | | < 2.4, and charm quark transverse momentum p c T > 5 GeV. The inclusive cross section for this kinematic range is (W + c) = 1026 31 (stat) +76 -72 (syst) pb. The cross section is also measured differentially as a function of the pseudorapidity of the muon from the W boson decay. These measurements are compared with theoretical predictions and are used to probe the strange quark content of the proton.
