The cross sections are evaluated integrated over a fiducial kinematic range and differentially as a function of the W decay lepton pseudorapidity and the Z boson rapidity. The integrated and the differential $W^{pm}$ and $Z/gamma$ cross sections are compared with perturbative QCD calculations, based on a number of different parton distribution sets available at NNLO.
