LHCb: Electroweak studies at LHCb

Results on the measurement of the $W^{\pm}$ and $Z^{0}$ cross-sections are presented using final state leptons with pseudorapidities between 2 and 4.5. Due to its acceptance, LHCb can probe a regime of low low-x electroweak boson production, where parton distribution functions are not well constrained. We summarize the $W^{\pm}$ measurements performed in the decay $\mu^{\pm}\nu$ and for the $Z^{0}$ in the channel $\mu^{+}\mu^{-}$ based on data collected by LHCb in 2010.
