Description
The mass of the W boson is a fundamental parameter of the Standard Model, providing a stringent test of its internal consistency. Its precise determination increasingly relies on measurements at hadron colliders, where effects related to nucleon structure and QCD corrections play a crucial role. Transverse Momentum Dependent (TMD) distributions offer a powerful framework to describe the three-dimensional structure of hadrons; however, their impact on the extraction of the W boson mass remains insufficiently explored. This talk will discuss ongoing efforts to investigate these effects using state-of-the-art TMD parametrizations and to quantify their impact on precision determinations of the W boson mass.
