LHCb: W and Z production at LHCb

Preliminary results are presented for the production cross-sections of $Z^0$ and $W^{\pm}$ production at the LHCb experiment. Also shown is the $W$ charge asymmetry as a function of lepton pseudo-rapidity. These measurements have particular interest because of the forward acceptance of the LHCb experiment, which covers pseudo-rapidities between approximately 2 and 5. The results may be interpreted as tests of the Standard Model, or can be used to constrain better the parton density functions. Prospects are given for improving these measurements in the forthcoming run, and for making complementary studies of Drell-Yan production to lower mass dilepton final states.
