description A search for new physics in events with a leptonically decaying Z boson and a large √ transverse momentum imbalance in proton-proton collisions collected at s = 13 TeVin 2016 with the Compact Muon Solenoid detector at the Large Hadron Collider is presented. The results of this search are interpreted in terms of a simplified model of darkmatter production via spin-0 or spin-1 mediators, a scenario with a standard-modellike Higgs boson produced in association with the Z boson and decaying invisibly, amodel of unparticle production, and a model with large extra spatial dimensions. Nosignificant deviations from the background expectations are found, and limits are seton relevant model parameters, significantly extending the results previously achieved in this channel.
