Abstract
A sample of W \rightarrow ev (W \rightarrow \mu v) and Z^0 \rightarrow e^+e^- (Z^0 \rightarrow \mu^+\mu^-) events recorded by the CDF detector for pp- collisions at \sqrt(s-hat) = 1:96 TeV with a total integrated luminosity of 2.3 fb^-1 are used to evaluate the systematic uncertainty in the determination of the W boson mass arising from uncertainties in the parton distribution functions and higher-order QCD effects. The systematic contribution of PDFs is determined to be 10 MeV for MSTW2008 NLO and 12 MeV for CTEQ6.6. The total systematic contribution arising from higher-order QCD eects in 9 MeV. The unfolded Z0 transverse momentum distribution is presented, and estimates of parameters in a phenomenological model describing low transverse momentum Z^0 events are extracted.
