Search for supersymmetry in proton-proton collisionsatps= 13TeV in events with high-momentum Zbosons and missing transverse momentum
A search for new physics in events with two highly Lorentz-boosted Z bosonsand large missing transverse momentum is presented. The analyzed proton-proton collisiondata, corresponding to an integrated luminosity of 137 fb-1, were recorded atps= 13 TeVby the CMS experiment at the CERN LHC. The search utilizes the substructure of jetswith large radius to identify quark pairs from Z boson decays. Backgrounds from standardmodel processes are suppressed by requirements on the jet mass and the missing transversemomentum. No signi cant excess in the event yield is observed beyond the number of back-ground events expected from the standard model. For a simpli ed supersymmetric modelin which the Z bosons arise from the decay of gluinos, an exclusion limit of 1920 GeV onthe gluino mass is set at 95% con dence level. This is the rst search for beyond-standard-model production of pairs of boosted Z bosons plus large missing transverse momentum.
