Differential cross sections for the production of Z bosons or off-shell photons γ∗ in association with jets are measured in proton-antiproton collisions at center-of-mass energy s=1.96TeV using the full data set collected with the Collider Detector at Fermilab in Tevatron run II and corresponding to 9.6fb-1 of integrated luminosity. Results include first measurements at CDF of differential cross sections in events with a Z/γ∗ boson and three or more jets, the inclusive cross section for production of Z/γ∗ and four or more jets, and cross sections as functions of various angular observables in lower jet-multiplicity final states. Measured cross sections are compared to several theoretical predictions.
