Invisible Decays of the Higgs Boson at CMS: Dark Matter and More
The experiments at the Large Hadron Collider at CERN are at the energy frontier of particle physics, searching for answers to fundamental questions of nature. In particular, dark matter presents strong evidence for physics beyond the standard model. In this talk, I will describe searches for invisible decays of the 125 GeV Higgs boson, predicted by several dark matter models. Searches for such beyond the standard model states can be carried out with the CMS experiment using missing energy signatures, exploiting various Higgs production modes. I will also discuss the prospects for discovering invisible decays of the Higgs boson at Run-3 of the LHC and the High Luminosity-LHC.
