W and Z production cross-sections have been measured in proton-proton collisions at a center-of-mass energy of 7 TeV using the decays W → μv, Z → μμ and Z → ττ collected by the LHCb detector. For all the measurements at least one of the reconstructed muons has a transverse momentum, pT, above 20 GeV/c and a pseudorapidity, η, between 2 and 4.5. In the case of the Z, a di-muon invariant mass between 60 GeV/c2 and 120 GeV/c2 is required. Theoretical predictions, calculated at next-to-next-to-leading order in QCD using recent parton distribution functions (PDFs), are found to be in agreement with the measurements.
