Abstract
The mass of the W-boson, mW , is a fundamental parameter of the Standard Model of particle physics. Its value is correlated with other observables of the theory and any deviation from the expectation would provide a striking hint of the possible existence of new physics. The measurement of mW represents an outstanding experimental challenge, requiring a deep understanding of both the detector and the theoretical uncertainties. In a proton-proton collider, such as the LHC, the uncertainty is dominated by the parton distribution functions (PDFs). This paper describes the potential and prospects of an ancillary measurement that is being carried out by the CMS Collaboration to constrain the PDF uncertainty on mW , namely the W-boson rapidity distribution as a function of its helicity state.
