Study of jets production association with a Z boson in pp collision at 7 and 8 TeV with the CMS detector
Abstract
This study presents the measurement of the rapidity distributions in events containing
a Z boson and a jet in proton-proton collisions at a center-of-mass energy of 7 TeV. The
data correspond to an integrated luminosity of approximately 5 fb−1 , recorded by the CMS
detector at the Large Hadron Collider (LHC). The measured angular distributions are com-
pared with the predictions from next-to-leading order perturbative QCD calculations and
two generator programs that combine tree-level matrix element calculations with parton
showers. We also present a measurement of jet production rates in association with a Z
boson using data recorded at a center-of-mass energy of 8 TeV and with an integrated lu-
minosity of 19.8 fb−1 . This measurement provides a stringent test of perturbative QCD
calculations, and the result is compared with predictions from theoretical calculations.
