Production of Gauge Bosons at the Tevatron

PDF Version Also Available for Download.

Description

The CDF and D0 collaborations have used recent data taken at the Tevatron to perform QCD tests with W and Z bosons decaying leptonically. D0 measures the production cross section times branching ratio for W and Z bosons and determines the branching ratio B(W {yields} l{nu}) = (10.43 {+-} 0.44)% (l = e, {mu}). This also gives an indirect measurement of the total width of the W boson: {Gamma}{sub W} = 2.16 {+-} 0.09 GeV. The W cross section times branching ratio into tau leptons is measured to be {sigma}({anti p}p {yields} W + X)B(W {yields} {tau}{nu}) = 2.38{+-}0.13 nb, ... continued below

Description

The CDF and D0 collaborations have used recent data taken at the Tevatron to perform QCD tests with W and Z bosons decaying leptonically. D0 measures the production cross section times branching ratio for W and Z bosons and determines the branching ratio B(W {yields} l{nu}) = (10.43 {+-} 0.44)% (l = e, {mu}). This also gives an indirect measurement of the total width of the W boson: {Gamma}{sub W} = 2.16 {+-} 0.09 GeV. The W cross section times branching ratio into tau leptons is measured to be {sigma}({anti p}p {yields} W + X)B(W {yields} {tau}{nu}) = 2.38{+-}0.13 nb, from which the ratio of the coupling constants is determined: g{sub {tau}}{sup W}/g{sub e}{sup W} = 1.004 {+-} 0.019 {+-} 0.026. D0`s measurement of the differential d{sigma}/dP{sub T} distribution for the Z boson decaying to electrons, discriminates between different phenomenologic vector boson production models. CDF measures the cross section for the Drell-Yan continuum, and extracts improved limits on compositeness scales for quarks and leptons of {Lambda}{sub ql} {approximately} 3 - 6 TeV, depending on the model. Studies of W + Jet production at CDF and D0 find that the QCD prediction underestimates the production rate of W + 1 Jet events by about a factor of 2 as measured by both collaborations.
