Book excerpt: 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].

Book excerpt: 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.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: We present a preliminary measurement of the[ital W] boson mass using data collected by the D[null] experiment at the Fermilab Tevatron during the 1994-1995 collider run 1b. We use[ital W][r-arrow][ital e][nu] decays to extract the[ital W] mass from the observed spectrum of transverse mass of the electron ([vert-bar][eta][vert-bar][lt] 1. 2) and the inferred neutrino We use[ital Z][sup 0][r-arrow][ital ee] decays to constrain our model of the detector response. We measure[ital m][sub W]/[ital m][sub Z]= 0.8815[+-] 0.0011([ital stat])[+-] 0.0014([ital syst]) and[ital m][sub W]= 80.38[+-] 0.07 ([ital W stat])[+-] 0.13([ital syst]) GeV. Combining this result with our previous measurement from the 1992-1993 data, we obtain[ital m][sub W]= 80.37[+-] 0.15 GeV (errors combined in quadrature).

Available in PDF, EPUB and Kindle. Book excerpt: The mass of the W boson is one of the most important parameters in the Standard Model. A precise measurement of the W boson mass, together with a precise measurement of the top quark mass, can constrain the mass of the undiscovered Higgs boson within the Standard Model framework or give a hint for physics beyond the Standard Model. This dissertation describes a measurement of the W boson mass through its decay into a muon and a neutrino using ~ 2.2 fb-1 of √ s = 1.96 TeV p$\bar{p}$ data taken with the CDF II detector at Fermilab. We measure the W boson mass to be (80.374 ± 0.015stat. ± 0.016syst.) GeV/c2. This result, when combined with the W mass measurement in the electron channel, leads to the single most precise mW value and greatly constrains the possible mass range of the undiscovered Higgs boson. iv.
