ICHEP / W mass measurement at LHCb

A significant displacement both from the electroweak fit predictions and previous experimental results has been observed in the recent measurement of the W boson mass at CDF. This confirms the importance of measuring this fundamental parameter of the Standard Model. The LHCb experiment has a fundamental role in this topic: it has recently measured the W boson mass by using a part of its available dataset, and plans to perform a more precise measurement with the full Run 2 dataset in the near future. Moreover, since this measurement is performed in a complementary phase space with respect to ATLAS and CMS, it will help in reducing the total uncertainty in a future LHC combination. In this talk the experimental aspects of the LHCb measurement are presented.
