Measurement of Z/γ* + jets differential cross sections with the CDF detector — •Stefano Camarda — DESY Notkestraße 85 22607 Hamburg, Germany
Differential Z/γ* + jets production cross sections in pp collisions at √s=1.96 TeV are measured with the full data sample collected with the CDF detector, corresponding to 9.6 fb−1 of integrated luminosity. Results include first measurements at CDF of differential cross sections in events with a Z/γ* and 3 or more jets, the inclusive cross section of Z/γ* + ≥ 4 jets production, and new distributions in the lower jet multiplicity final states. Measured cross sections are compared to several theoretical predictions, among which perturbative QCD predictions at next-to-leading order (NLO) and approximate nNLO, event generators based on LO and NLO matrix elements matched to parton showers, and perturbative NLO QCD predictions including NLO electro-weak corrections.
