Abstract

where the first uncertainty is statistical, the second is systematic and the third is due to the luminosity determination. Cross-section ratios and differential distributions as functions of the muon pseudorapidity are also presented. The ratio of W+ to W− cross-sections in the same fiducial kinematic region is determined to be(formula presented.).where the uncertainties are statistical and systematic, respectively. Results are in good agreement with theoretical predictions at next-to-next-to-leading order in perturbative quantum chromodynamics.[Figure not available: see fulltext.Abstract: A measurement of the inclusive W → μν production cross-section using data from pp collisions at a centre-of-mass energy of (formula presented.) TeV is presented. The analysis is based on an integrated luminosity of about 1.0 fb−1 recorded with the LHCb detector. Results are reported for muons with a transverse momentum greater than 20 GeV/c and pseudorapidity between 2.0 and 4.5. The W+ and W− production cross-sections are measured to be(formula presented.).
