Abstract
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.
