Abstract
We present a measurement of at , using electrons identified in the forward region () of the CDF II detector, in of data. We measure . Combining this result with a previous CDF measurement obtained using electrons in the central region (), we present the first measurement of the ratio of central-electron to forward-electron partial cross sections , consistent with theoretical predictions using Coordinated Theoretical-Experimental Project on QCD (CTEQ) and Martin-Roberts-Stirling-Thorne (MRST) parton distribution functions.
