The production of heavy flavour in association with a W or Z boson represents an important process to study QCD. High precision is achieved in measurements of differential cross sections and comparisons are made to state­of­the­art NLO QCD calculations. Measurement of W+c production cross section has a unique sensitivity to the strange­quark density, which is poorly known at low x. W+b production, on the other hand, probes the b­quark production by higher order QCD processes. Cross sections are measured differentially as a function of jet multiplicity and transverse momentum of the leading b­jet, for the W+b measurement and as a function of lepton pseudorapidity for the W+c measurement.
