Book excerpt: 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 sqrt(s) = 13 TeV in 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 dark matter production via spin-0 or spin-1 mediators, a scenario with a standard-model-like Higgs boson produced in association with the Z boson and decaying invisibly, a model of unparticle production, and a model with large extra spatial dimensions. No significant deviations from the background expectations are found, and limits are set on relevant model parameters, significantly extending the results previously achieved in this channel.
