  Measurements of the total and differential fiducial cross sections for the Z
boson decaying into two neutrinos are presented at the LHC in proton-proton
collisions at a center-of-mass energy of 13 TeV. The data were collected by the
CMS detector in 2016 and correspond to an integrated luminosity of 35.9
fb$^{-1}$. In these measurements, events are selected containing an imbalance
in transverse momentum and one or more energetic jets. The fiducial
differential cross section is measured as a function of the Z boson transverse
momentum. The results are combined with a previous measurement of
charged-lepton decays of the Z boson.
