Abstract:<\/b><\/p>\n

We present the status of the determination of the W boson mass at hadron colliders, discussing the main sources of uncertainty, in a theory perspective, reviewing the results from the Tevatron and LHC experiments. We then introduce a new observable, arXiv:2301.04059 , sensitive to the W boson mass, whose features are particularly suitable for a systematic discussion of the different uncertainties affecting the MW determination.<\/p>\n

We demonstrate that one of the most problematic elements in the modelling of the kinematical distributions, namely the perturbative QCD corrections, is under control, with a residual uncertainty at the +-5 MeV level.<\/p>\n
