    Abstract:
    We present a measurement of the cross section for W-boson production in association with jets in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ 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 dsigma($p\bar{p}$-->W+>=n-jet)/dETnth-jet×[script B](W-->enu) with respect to the transverse energy ET of the nth-highest ET jet above 20 GeV, and the total cross section sigma($p\bar{p}$-->W+>=n-jet;ETnth-jet>25 GeV)×[script B](W-->enu), for a restricted W-->enu 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.
