Search for dark matter particles produced in association with a Higgs boson in proton-proton collisions at root s=13TeV
A search for dark matter (DM) particles is performed using events with a Higgs boson candidate and large missing transverse momentum. The analysis is based on protonproton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC in 2016, corresponding to an in...

| Summary: | A search for dark matter (DM) particles is performed using events with a Higgs
boson candidate and large missing transverse momentum. The analysis is based on protonproton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment
at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb−1
. The search
is performed in five Higgs boson decay channels: h → bb, γγ, τ
+
τ
−
, W+W−
, and ZZ.
The results from the individual channels are combined to maximize the sensitivity of the
analysis. No significant excess over the expected standard model background is observed
in any of the five channels or in their combination. Limits are set on DM production
in the context of two simplified models. The results are also interpreted in terms of a
spin-independent DM-nucleon scattering cross section and compared to those from directdetection DM experiments. This is the first search for DM particles produced in association
with a Higgs boson decaying to a pair of W or Z bosons, and the first statistical combination
based on five Higgs boson decay channels |
