Description
We present a measurement of σ(pp→W)xB(W→eν) at √(s)=1.96 TeV, using electrons identified in the forward region (1.2< vertical bar η vertical bar <2.8) of the CDF II detector, in 223 pb-1 of data. We measure σxB=2796±13(stat)-90+95(syst)±162(lum) pb. Combining this result with a previous CDF measurement obtained using electrons in the central region ( vertical bar η vertical bar < or approx. 1), we present the first measurement of the ratio of central-electron to forward-electron W partial cross sections Rexp=0.925±0.006(stat)±0.032(syst), consistent with theoretical predictions using Coordinated Theoretical-Experimental Project on QCD (CTEQ) and Martin-Roberts-Stirling-Thorne (MRST) parton distribution functions
