Recent Electroweak Results from the Tevatron

Description: W and Z bosons are mainly produced via quark-antiquark annihilations at the Fermilab Tevatron collider. Precision measurements with these gauge bosons provide us with high precision tests of the Standard Model (SM) as well as indirect search for possible new physics beyond the SM. I present the recent electroweak measurements related to single W, Z boson and diboson productions from the CDF and D0 experiments at the Fermilab Tevatron collider.

A precision measurement of the w boson mass at D0

Description: 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{sup -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 measurem… more

Direct measurement of the W boson decay width in proton-antiproton collisions at s**(1/2) = 1.96-TeV

Description: This dissertation describes a direct measurement of the W boson total decay width, {Lambda}{sub W}, using the D0 detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb{sup -1} data, collected during the 2002-2003 run. The width is determined from the shape of the transverse mass distribution, M{sub T}, by fitting the data in the tail region 100 < M{sub T} < 200 GeV. The result if {Lambda}{sub W} = 2.011 {+-} 0.093(stat) {+-} 0.107(syst) GeV.

Electroweak and QCD Results from the Tevatron

Description: The Tevatron collider has been remarkably successful and has so far delivered more than 11 fb{sup -1} of data to both the CDF and D0 experiments. Though the LHC has replaced the Tevatron as the world's most powerful collider, years of detector calibration, the huge size of the dataset and the nature of pp collisions will keep the Tevatron competitive in many selected topics in the near future. More than 10 fb{sup -1} of data has been collected by each experiment. Good understanding of the detec… more
