Sumario:Recent results on W and Z physics from LHC experiments are presented. Measurements reviewed include total W and Z cross sections, W lepton charge asymmetry, and Z di ff erential cross sections. Production of Z bosons is studied as a function of rapidity, transverse momentum and angular variables. The Drell-Yan di ff erential distribution with the dilepton mass and the double di ff erential distribution with the dilepton mass and rapidity are shown. Finally, measurements of several electroweak observables, the forward-backward Drell- Yan asymmetry and the sin θ W are also presented. The measurements are compared with theoretical predictions using the most accurate theoretical predictions and modern parton distribution functions. A general agreement is observed.
