Description
The production of a { {Z}} boson, decaying to two charged leptons, in
association with jets in proton-proton collisions at a centre-of-mass
energy of 13 {TeV} is measured. Data recorded with the CMS detector at
the LHC are used that correspond to an integrated luminosity of 2.19
{fb}^ {-1}. The cross section is measured as a function of the jet
multiplicity and its dependence on the transverse momentum of the { {Z}}
boson, the jet kinematic variables (transverse momentum and rapidity),
the scalar sum of the jet momenta, which quantifies the hadronic
activity, and the balance in transverse momentum between the
reconstructed jet recoil and the { {Z}} boson. The measurements are
compared with predictions from four different calculations. The first
two merge matrix elements with different parton multiplicities in the
final state and parton showering, one of which includes one-loop
corrections. The third is a fixed-order calculation with
next-to-next-to-leading order accuracy for the process with a { {Z}}
boson and one parton in the final state. The fourth combines the fully
differential next-to-next-to-leading order calculation of the process
with no parton in the final state with next-to-next-to-leading logarithm
resummation and parton showering.
