Аннотация: A measurement is presented of the production of Z bosons that decay into two electrons or muons inassociation with jets, in proton-proton collisions at a center-of-mass energy of 13 TeV. The data wererecorded by the CMS Collaboration at the LHC with an integrated luminosity of 35.9 fb−1. The differentialcross sections are measured as a function of the transverse momentum (p_T) of the Z boson and the transverse momentum and rapidities of the five jets with largest p_T. The jet multiplicity distribution is measured for up to eight jets. The hadronic activity in the events is estimated using the scalar sum of the p_T of all the jets. All measurements are unfolded to the stable-particle level and compared with predictions from various Monte Carlo event generators, as well as with expectations at leading and next-to-leading orders in perturbative quantum chromodynamics.
