The Collider Detector at Fermilab (CDF) was used to measure the transverse momentum distribution of W boson produced in proton-antiproton collisions at the Tevatron collider. The W bosons were identified by the decay W 2!e[nu]. The results are in good agreement with a next-to-leading order calculation. The cross section for W production with P{sub T}> 50 GeV/c is 423 {plus minus} 58 (stat.) {plus minus} 108 (sys.) pb. 58 refs., 53 figs., 16 tabs.

We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy √s=8 TeV, corresponding to an integrated luminosity of 19.7 fb-1. The Z boson is identified via its decay to a pair of muons. The measurement provides a precision test of quantum chromodynamics over a large region of phase space. In addition, due to the small experimental uncertainties in the measurement the data has the potential to constrain the gluon parton distribution function in the kinematic regime important for Higgs boson production via gluon fusion. The results agree with the next-to-next-to-leading-order predictions computed with the fewz program. The results are also compared to the commonly used leading-order MadGraph and next-to-leading-order powheg generators.

I report the results of an analysis to measure the mass and width of the Z gauge boson from Z $to$ e$sp{+}$e$sp{-}$ decays in pp collisions at $sqrt{s}$ = 1.8 TeV. The Z $to$ e$sp{+}$e$sp{-}$ data from the CDF detector yields a mass of the Z boson of M$sb{rm Z}$ = 90.78 $pm$ 0.40(stat.) $pm$ 0.38(syst.) $pm$ 0.2(scale) GeV/c$sp2$ and a width of $Gammasb{rm Z}$ = 2.8 $pm$ 1.0(stat.) $pm$ 0.5(syst.) GeV.
