Differential Z + jet cross section measurements at 8 TeV

Abstract

The measurement of differential cross section of a Z boson produced in association with jets is presented. The cross section is presented with respect to various jet kinematic variables where the Z bosons are reconstructed from opposite sign lepton pairs. The analysis is based on data of proton proton collisions with the centre of mass energy of 8 TeV collected in 2012 by the CMS experiment at LHC corresponding to 19.8 /fb of integrated luminosity. Obtained results are compared with different generators and are shown to be consistent with the Standard Model predictions.
