Description
Measurement of W+c production cross section has a unique sensitivity to the strange-quark density, which is poorly known at low x. W+b production, on the other hand, probes the b-quark production by higher order QCD processes. Cross sections are measured differentially as a function of jet multiplicity and transverse momentum of the leading b-jet, for the W+b measurement and as a function of lepton pseudorapidity for the W+c measurement. The results are compared to the QCD predictions at NLO.
