Abstract

The cross section for the inclusive production of W bosons in association with jets in ppbar collisions at sqrt(s)=1.96 TeV using the Collider Detector at Fermilab (CDF II) is presented. The measurement is based on an integrated luminosity of 320pb-1, and includes events with up to 4 or more jets. In each jet multiplicity sample the differential and cumulative cross sections with respect to the transverse energy of the ith-jet are measured. For W+>=2 jets the differential cross section with respect to the 2-leading jets invariant mass mj1j2 and angular separation Delta Rj1j2 is also reported. The data are compared to predictions from Monte Carlo simulations.
