Abstract We present a measurement of the cross section for W-boson production in association with jets in pbarp collisions at √s = 1.96 TeV. The analysis uses a data sample corresponding to an integrated luminosity of 320 pb-1 collected with the CDF II detector. W bosons are identified in their electron decay channel and jets are reconstructed using a cone algorithm. For each W+>= n-jet sample (n= 1 - 4) we measure sigma(ppbar ->W+>=n-jet)x BR(W -> e nu) with respect to the transverse energy E_T of the nth-highest ET jet above 20 GeV, for a restricted W -> e nu decay phase space. The cross sections, corrected for all detector effects, can be directly compared to particle level W+ jet(s) predictions. We present here comparisons to leading order and next-to-leading order predictions.
