First measurement of the ratio of central-electron to forward-electron W partial cross sections in pp̄ collisions at s=1.96TeV

First measurement of the ratio of central-electron to forward-electron W partial cross sections in pp̄ collisions at s=1.96TeV

We present a measurement of σ(pp̄→W)×B(W→eν) at s=1.96TeV, using electrons identified in the forward region (1.2<|η|<2.8) of the CDF II detector, in 223pb-1 of data. We measure σ×B=2796±13(stat)-90+95(syst)±162(lum)pb. Combining this result with a previous CDF measurement obtained usin...
