Description
We report the LHC measurements of single W and Z boson production at different centre-of-mass energies. Together, the ATLAS, CMS and LHCb detectors provide precision coverage over an absolute rapidity range from 0 to 4.5, enabling precision studies of Standard Model physics across different kinematic regions. We report both differential cross-sections and ratios of W boson and Z boson measurements. These results allow tests of the performance of different parton distribution functions (PDFs), and can be used to further constrain the PDFs. In addition, the results are compared to predictions from different Monte Carlo generators, testing different approaches to modelling QCD effects. We also report measurements of the forward-backward asymmetry in Z boson decays, and measurements of angular coefficients, which provide sensitivity to the electroweak mixing angle.
