Abstract We present preliminary results on the W+jets production in p-pbar collisions at sqrt(s)=1.96 TeV using data collected with the CDF Run II detector corresponding to an integrated luminosity of 2.8 fb-1. We measure several differential cross sections including the inclusive n jet cross section, the nth leading jet transverse momentum (pT), the dijet separation (Rjj) and mass (mjj). In addition, we measure cross section shapes (our differential cross sections normalized to the integrated jet multiplicity cross section) as well as ratio observables between different jet multiplicities. Jets are reconstructed using the Midpoint algorithm with cone size of R=0.4 and all measurements are corrected to the hadron level.
