Measurement of the W -boson production cross sections in p p collisions at s = 13 TeV in the forward region

R. Aaij · M. Abdelfatah · A. S. W. Abdelmotteleb · C. Abellan Beteta · y 196 más

A precision measurement of the W -boson production cross section is performed using the W → μ ν decay channel, based on a sample of proton-proton collision data collected by the LHCb experiment at s = 13 TeV and corresponding to an integrated luminosity of 5.1 fb − 1 . The cross section is measured for muons with trans...
