Studies of EW Boson Production in the Forward Region with LHCb
We report on measurements of W$^+$, W$^-$ and Z$^0$ production, using data taken by the LHCb experiment at $\sqrt{s}$ = 7 TeV during 2010. The electroweak bosons are reconstructed by selecting decays to muonic final states. The cross-sections are measured within the region 2 < $\eta$ < 4.5, us...

description | We report on measurements of W$^+$, W$^-$ and Z$^0$ production, using data taken by the LHCb experiment at $\sqrt{s}$ = 7 TeV during 2010. The electroweak bosons are reconstructed by selecting decays to muonic final states. The cross-sections are measured within the region 2 < $\eta$ < 4.5, using muons of transverse momenta exceeding 20 GeV/c, as well as differentially as a function of lepton pseudorapidity (for W) and boson rapidity (for Z). Measurements of the W charge asymmetry as a function of lepton pseudorapidity are obtained for different lepton transverse momentum thresholds in the same forward region, providing constraints on the u and d valence partons. Results are compared to NLO and NNLO predictions. |
