measurement is presented of the production of Z bosons that decay into two electrons or muons in
association with jets, in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were
recorded by the CMS Collaboration at the LHC with an integrated luminosity of 35.9 fb −1 . The differential
cross 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 pT . 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.
