Measurement of the W boson production charge asymmetry in p$$\bar{p}$$ collisions
- Univ. of Rochester, NY (United States)
We present a measurement of the W boson production charge asymmetry using the W → ev decay channel. We use data collected the Collider Detector at Fermilab (CDF) from p$$\bar{p}$$ collisions at √s = 1.96 TeV. The data were collected up to February 2006 (Run II) and represent an integrated luminosity of 1 fb-1. The experimental measurement of W production charge asymmetry is compared to higher order QCD predictions generated using MRST2006 and CTEQ6 parton distribution functions (PDF). The asymmetry provides new input on the momentum fraction dependence of the u and d quark parton distribution functions (PDF) within the proton over the fraction of proton's momentum range from 0.002 < x < 0.8 corresponding to -3.0 < yW < 3.0 at Q2 ~ MW2.
