Search for dark matter in $\mathrm{Z}+E_\mathrm{T}^\mathrm{miss}$ events using $12.9~\mathrm{fb}^{-1}$ of 2016 data

A search for new physics in events with a Z boson produced in association with large missing transverse momentum with the CMS experiment at the LHC is presented. This search is interpreted in a simplified model with a spin-1 dark matter mediator and in a model with a standard model Higgs-like scalar particle, each produced in association with the Z boson and decaying invisibly. The search is based on a 2016 data sample of proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$ corresponding to an integrated luminosity of $12.9~\mathrm{fb}^{-1}$.
