The W boson mass (mW) is a key parameter of the standard model, constraining the mass of the unobserved Higgs boson. Using Tevatron ppbar collision data from 1992-1996, the CDF and D0 collaborations measured mW to a precision of 59 MeV. The…

We investigate the posibility of improving the W mass measurement at ATLAS. Given the high statistics of both W and Z bosons expected at the LHC, we estimate that a precision of 7 MeV per channel can be reached with 10 fb-1 of data.
In the standard model of particle physics, the masses of the W and Z bosons, the carriers of the weak interaction, are uniquely related. A precise determination of their masses is important because quantum loops of heavy, undiscovered…
