In this talk, we will present a search for dark matter via the mono-h(bb) channel using the 2016 data collected by the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). The mono-h(bb) signal is characterized by a large missing transverse momentum recoiling against a Higgs boson decaying to a bottom quark-antiquark pair. Novel analysis techniques are exploited. The number of events observed in the data is consistent with the standard model background prediction. Results are interpreted in terms of limits on parameters of various mono-higgs models. We will also present the first statistical combination based on five Higgs boson decay channels.
