Measurement of differential production cross section for $Z/{\gamma }^{\ast }$ bosons in association with jets in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV

Abstract

Differential cross sections for the production of $Z$ bosons or off-shell photons ${\gamma }^{\ast }$ in association with jets are measured in proton-antiproton collisions at center-of-mass energy $\sqrt{s}=1.96$ TeV using the full data set collected with the Collider Detector at Fermilab in Tevatron Run II, and corresponding to 9.6 fb${}^{-1}$ of integrated luminosity. Results include first measurements at CDF of differential cross sections in events with a $Z/{\gamma }^{\ast }$ boson and three or more jets, the inclusive cross section for production of $Z/{\gamma }^{\ast }$ 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.
