Hunting the Dark Higgs at CMS — •Samuel Baxter1,2, Alexander Grohsjean1, Christian Schwanenberger1, and Oliver Buchmüller21Deutsches Elektronen-Synchrotron DESY, Hamburg, Germany — 2Imperial College London, London, England

The dark Higgs model is an extension of the Standard Model (SM) that describes the phenomenology of dark matter while respecting the SM gauge symmetries.
Besides adding a fermionic dark matter candidate to the SM, it introduces a new vector boson (Z’) along with a new scalar, the dark Higgs particle.
This new approach provides several advantages over other so-called simplified models of dark matter which will be discussed in this talk.
Moreover, a first search using 36fb−1 of proton-proton data recorded in 2016 by the CMS experiment, which is part of the LHC at CERN, will be presented.
