Recent results from LEP experiments have substantially improved the knowledge of the Z boson. However, hadron colliders remain the only source of direct measurements of the W boson. There have been measurements of the W boson mass from the UA2 and CDF collaborations. The W mass continues to be a subject of great interest in testing the Standard Model. Here, the authors have made a preliminary determination of the W boson mass M[sub W] = 80.38 [+-] 0.23 GeV/c[sup 2] from a combined analysis of W [yields] e[nu] and W [yields] [mu][nu] in [anti p]p collisions at [radical]s = 1.8 TeV. The electron data alone yields M[sub W] = 80.47 [+-] 0.15(stat.) [+-] 0.25(syst.) GeV/c[sup 2], while the muon data gives M[sub W] = 80.29 [+-] 0.20(stat.) [+-] 0.24(syst.) GeV/c[sup 2].

I present the first measurement of the W boson mass in the electron decay channel using the Run II D0 detector at the Fermilab Tevatron Collider. The data used was collected from 2002 to 2006 and the integrated luminosity is 1 fb−1. The W boson mass was determined from the likelihood fit to the measured data distribution. The mass value is found to be 80.401 ± 0.023(stat) ± 0.037(syst) GeV = 80.401 ± 0.044 GeV using the transverse mass spectrum, which is the most precise measurement from one single experiment to date. This result puts tighter constraints on the mass of the standard model Higgs boson. I also present three other measurements that can help to reduce the theoretical uncertainties for the future W mass measurements.

This thesis describes a measurement of the W boson mass with the ATLAS detector based on the data-set recorded by ATLAS in 2011 at a centre-of-mass energy of 7 TeV, and corresponding to 4.6 inverse femtobarn of integrated luminosity. Measurements are performed through template fits to the transverse momentum distributions of charged leptons and to transverse mass distributions of the W boson, in electron and muon decay modes in various kinematic categories. The individual measurements are found to be consistent and their combination leads to a value of m_W = 80371.1 ± 18.6 MeV. The measured value of the W boson mass is compatible with the current world average of m_W = 80385 ± 15 MeV. The uncertainty is competitive with the current most precise measurements performed by the CDF and D0 collaborations.

We describe a measurement of the W boson mass m{sub W} using 200 pb−1 of √s = 1.96 TeV p{bar p} collision data taken with the CDF II detector. With a sample of 63,964 W → e[nu] candidates and 51,128 W → [mu][nu] candidates, we measure m{sub W} = [80.413 ± 0.034(stat.) ± 0.034 (sys.) = 80.413 ± 0.048] GeV/c2. This is the single most precise m{sub W} measurement to date. When combined with other measured electroweak parameters, this result further constrains the properties of new unobserved particles coupling to W and Z bosons.
