We present a new measurement of the $W$ mass using the $W\to e\nu$ data from the D\O forward detectors at the Fermilab Tevatron $p \bar p$ Collider. This is the first measurement of the $W$ mass with electron candidates in the range $1.5 <…

We present a measurement of the W boson mass using data collected by the D0 experiment at the Fermilab Tevatron during 1994--1995. We identify W bosons by their decays to $e\nu$ final states. We extract the W mass, M(W), by fitting the…

We present a measurement of the W boson mass in W -> ev decays using 1 fb^-1 of data collected with the D0 detector during Run II of the Fermilab Tevatron collider. With a sample of 499830 W -> ev candidate events, we measure M_W = 80.401…

I present a measurement of the W boson mass (M_W) and width (G_W) using 200 and 350 pb-1 of CDF Run II data respectively. The measurements, performed in both the electron and muon decay channels, rely on a fit to the W transverse mass…

I describe the latest D0 and CDF W boson mass measurements. The D0 measurement is performed with $4.3\, fb^{-1}$ of integrated luminosity in the electron decay channel with a data set of $1.68\times 10^{6}$ W candidates. The value of the W…

A measurement of the mass of the W boson is presented which is based on a sample of 5982 W -> e nu decays observed in pbar-p collisions at sqrt(s) = 1.8 TeV with the D0 detector during the 1992-1993 run. From a fit to the transverse mass…

Precise measurements of the mass and width of the W boson are sensitive to radiative corrections and can be used to place limits on new physics beyond the Standard Model and validate the consistency of the model. In particular, the W boson…
