Measurement of the W Boson Mass with 1 fb − 1 of D 0 Run II Data
نویسنده
چکیده
We present the most precise single measurement of the W boson mass using data collected with the D0 experiment. An integrated luminosity of 1 fb −1 yields 499,830 W → eν candidates. With this sample we measure M W = 80.401 ± 0.043 GeV.

Update of the Combination of CDF and D 0 Results for the Mass of the W Boson The Tevatron Electroweak Working Group ∗ for the CDF and D 0 Collaborations
We summarize and combine the results on the direct measurements of the mass of the W boson in data collected by the Tevatron experiments CDF and D0 at Fermilab. Earlier of Run-II data are now combined with two new, high statistics Run-II measurements: a CDF measurement in both electron and muon channels using 2.2 fb −1 of integrated luminosity collected between 2002 and 2007, and a D0 measureme...

We summarize and combine the results on the direct measurements of the mass of the W boson in data collected by the Tevatron experiments CDF and D0 at Fermilab. Results from CDF Run-0 (1988-1889) and Run-I (1992-1995) have been combined with D0 results from Run-I, the CDF 200 pb −1 published results from the first period of Run-II (2001-2004) and the recent 1 fb −1 result in the electron channe...
متن کاملMeasurement 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.
متن کاملA 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...
