Measurement of the Z boson differential production cross section using its invisible decay mode (Z → νν¯¯¯) in proton-proton collisions at s√ = 13 TeV

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. The measured total fiducial cross section for events with Z boson transverse momentum greater than 200 GeV is 3000 $^{; ; ; ; +180}; ; ; ; _{; ; ; ; -170}; ; ; ; $ fb.
