Jets produced in association with Z-bosons in CMS at the LHC

A study of jet production in association with a Z boson in proton-proton collisions at a 7 TeV center-of-mass energy is presented, using data collected with the CMS detector during the 2010 LHC collisions run, corresponding to an integrated luminosity of 36.1 pb^{-1}. The measured jet multiplicity distributions are corrected for efficiency and unfolded for detector effects to be directly comparable with theoretical predictions. The leading reconstructed jet transverse energy distributions are measured, unfolded and compared with theoretical predictions. Ratios of Z+>=n-jets/Z+>=(n-1)-jets and Z+>=n-jets/Z+>=0-jets versus the exclusive n reconstructed jets are also presented.
