Description
The forward acceptance of the LHCb detector provides unique sensitivity to parton distribution functions in kinematic regions complementary to those probed by other LHC experiments. This talk reviews electroweak measurements at LHCb and their role in constraining proton structure. Particular attention is given to the interplay between PDF uncertainties and precision electroweak observables: quantities such as the W boson mass and the effective leptonic weak mixing angle are increasingly limited by knowledge of the proton's partonic content, while LHCb production measurements offer constraining power on the same distributions. Recent results are presented alongside prospects for forthcoming measurements with Run 3 data, and the potential for dedicated forward measurements to reduce PDF uncertainties in future precision tests of the Standard Model is discussed.
