| description | A search for dark matter produced in association
with a Higgs boson decaying to a pair of bottom quarks is
performed in proton–proton collisions at a center-of-mass
energy of 13 TeV collected with the CMS detector at the
LHC. The analyzed data sample corresponds to an integrated luminosity of 35.9 fb−1. The signal is characterized
by a large missing transverse momentum recoiling against
a bottom quark–antiquark system that has a large Lorentz
boost. The number of events observed in the data is consistent with the standard model background prediction. Results
are interpreted in terms of limits both on parameters of the
type-2 two-Higgs doublet model extended by an additional
light pseudoscalar boson a (2HDM+a) and on parameters of
a baryonic Z simplified model. The 2HDM+a model is tested
experimentally for the first time. For the baryonic Z model,
the presented results constitute the most stringent constraints
to date. |
