Inclusive Jet Production in Z+jets final states at CDF

We present preliminary results on the measurement of the inclusive Z-boson plus jet(s) production cross section, in a final state where the Z-boson has decayed in two muons. We used $\sim 5$ fb$ ^{-1}$ data in $\rm p\bar{p}$ collisions at $\rm \sqrt{s}$ = 1.96 TeV collected by the CDF Run II experiment. Differential cross sections as a function of jet transverse momentum and jet multiplicity are compared to NLO pQCD predictions.
