چکیده

We present a measurement of the W boson mass using data collected with the CDF detector during the 1994-95 collider run at the Fermilab Tevatron. A fit to the transverse mass spectrum of a sample of 30,115 W → eν events recorded in an integrated luminosity of 84 pb−1 gives a mass MW = 80.473 ± 0.065(stat.) ± 0.092(syst.) GeV/c2. A fit to the transverse mass spectrum of a sample of 14,740 W → μν events from 80 pb−1 gives a mass MW = 80.465 ± 0.100(stat.) ± 0.103(syst.) GeV/c2. The dominant contributions to the systematic uncertainties are the uncertainties in

Measurement of the W boson mass.

We present a measurement of the W boson mass in W-->e(nu) 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-->e(nu) candidate events, we measure M(W)=80.401+/-0.043 GeV. This is the most precise measurement from a single experiment.

A Precision Measurement of the W Boson Mass with 1 Fb−1 of Dø Run Iia Data

by Jyotsna Osta This thesis is a detailed presentation of a precision measurement of the mass of the W boson. It has been obtained by analyzing W → eν decays. The data used for this analysis was collected from 2002 to 2006 with the DØ detector, during Run IIa of the Fermilab Tevatron collider. It corresponds to a total integrated luminosity of 1 fb−1. With a sample of 499,830 W → eν candidate e...

Direct measurement of the W boson width.

We present a direct measurement of the width of the W boson using the shape of the transverse mass distribution of W --> enu candidate events. Data from approximately 1 fb(-1) of integrated luminosity recorded at square root of s = 1.96 TeV by the D0 detector at the Fermilab Tevatron pp collider are analyzed. We use the same methods and data sample that were used for our recently published W bo...

Measurement of Properties of Electroweak Bosons with the DØ Detector

This article reports three analyses of W and Z boson properties from the DØ experiment at the Fermilab Tevatron. The W boson mass measurement using 1 f b −1 DØ data is presented. This measurement reaches a 43 MeV precision on the W boson mass, which is currently the most precise result from a single experiment. It is used to place indirect constraint on the mass of the hypothetical Higgs boson....

2 8 Ja n 20 03 W Charge Asymmetry Measurement in CDF Run 2

We present the status of the forward-backward charge asymmetry measurement for W boson production using early Run 2 data collected with the Collider Detector at Fermilab (CDF). Tracking for forward electrons is a critical component of this measurement, and we describe a new technique which combines the position and energy measurements from the calorimeter with position measurements in the silic...
