Hunting the Dark Higgs at CMS — •Samuel Baxter1,2, Alexander Grohsjean1, Christian Schwanenberger1, and Oliver Buchmüller2 — 1Deutsches Elektronen-Synchrotron DESY, Hamburg, Deutschland — 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 opens regions of parameter space that are not covered by searches with simpler models of dark matter.
The result of a 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.
