Electroweak boson production in the forward region with LHCb

We have measured the W and Z boson production cross-sections in proton-proton collisions at a centre-of-mass energy of 7~TeV, using datasets of up to 240$\pm 8$~pb$^{-1}$ collected by the LHCb experiment. All measurements are based on boson decays with at least one muon in the final state, which...

description We have measured the W and Z boson production cross-sections in proton-proton collisions at a centre-of-mass energy of 7~TeV, using datasets of up to 240$\pm 8$~pb$^{-1}$ collected by the LHCb experiment. All measurements are based on boson decays with at least one muon in the final state, which has transverse momentum $p_{T\mu}$ exceeding 20~GeV and pseudorapidity $\eta_{\mu}$ within $2.0 - 4.5$. Z bosons are reconstructed in decays to muon or tau lepton pairs (the latter reconstructed in final states involving two muons, and one muon and one electron, within the same fiducial aceptance), where the reconstructed invariant mass $m_{Z}$ lies in the range $60 \leq m_{Z} \leq 120$~GeV. In all cases results are consistent with next-to-next-to-leading order theoretical predictions.
