Abstract

Measurements are presented of associated production of a W boson and a charm quark (W+c) in proton-proton 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)±→ D0 + π±→ K∓ + π± + π±. A cross section is measured in the fiducial region defined by the muon transverse momentum pμT> 26 GeV, muon pseudorapidity |ημ|< 2.4, and charm quark transverse momentum pcT> 5 GeV. The inclusive cross section for this kinematic range is σ(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.
