Search for new physics in events with a leptonically decaying Z boson and a large transverse momentum imbalance in proton-proton collisions at root s=13 TeV
A search for new physics in events with a Z boson produced in association with large missing transverse momentum at the LHC is presented. The search is based on the 2016 data sample of proton-proton collisions recorded with the CMS experiment at √s = 13 TeV, corresponding to an integrated lumino...

| Summary: | A search for new physics in events with a Z
boson produced in association with large missing transverse
momentum at the LHC is presented. The search is based on
the 2016 data sample of proton-proton collisions recorded
with the CMS experiment at √s = 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. 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. |
