I present measurements of the W boson charge asymmetry and the W boson width (Γ W) using 350 pb-1 of CDF Run II data. The charge asymmetry is the first direct measurement, which uses a new technique to reconstruct the W rapidity by constraining its mass; the result will further constrain Parton Distribution Functions in future fits. The width measurement relies on a fit to the W transverse mass distribution. We measure Γ W = 2032 ± 71 MeV which is in good agreement with the Standard Model…

First measurements of inclusive W and Z cross sections from run II of the fermilab tevatron collider.
We report the first measurements of inclusive W and Z cross sections times leptonic branching ratios for pp collisions at square root[s]=1.96 TeV, based on their decays to electrons and muons. The…
New generation of parton distributions with uncertainties from global QCD analysis
A new generation of parton distribution functions with increased precision and quantitative estimates of uncertainties is presented. This work signiflcantly extends previous CTEQ and other global…
Soft gluon effects on lepton pairs at hadron colliders
We consider the Collins-Soper-Sterman resummation formalism, which describes the vector boson transverse momentum ${(Q}_{T})$ distribution at hadron colliders, and extend it for the distributions of…
Hard photon effects inW± andZ0 decay
AbstractThe effects of QED radiative corrections to the processes $$p\bar p \to W^ \pm \to lv$$ and $$p\bar p \to Z_O \to l\bar l$$ are discussed. The purpose is twofold. On one hand the rate for…
QED radiative corrections and radiative decays of the intermediate weak bosons produced in proton-antiproton collisions
We present here a detailed description of the calculations of QED radiative corrections to the decays ofW andZ bosons. A comparison is made with experimental data. In particular it is shown that it…
