摘要：

We present a measurement of the cross section for W-boson production in association with jets in p (p) over bar collisions at root 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 the differential cross section d sigma(p (p) over bar -> W+>= n-jet)/dE(T)(nth-jet)xB(W -> e nu) with respect to the transverse energy E-T of the nth-highest E-T jet above 20 GeV, and the total cross section sigma(p (p) over bar -> W+>= n-jet;E-T(nth-jet)> 25 GeV)xB(W -> e nu), 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.
