Precision measurements of W properties at LHC
Abstract
Exploiting the large number of collected events and the symmetries in the W production and decay at LHC, it is possible to measure the W double differential cross section of transverse momentum and rapidity and the angular coefficients. With the proposed method a determination of the integrated spectrum of transverse momentum of W bosons is possible with an unprecedented granularity and increased precision with respect to the state-of-the-art generators. This enables the possibility to perform a theory-agnostic measurement of the W mass with competitive uncertainty by constraining the W production directly on data. This paper shows preliminary results derived on a subset of events collected by CMS during Run 2, for an integrated luminosity of 36 fb-1.
