DESCRIPTION:Speakers: Marina Pokidova (NRC Kurchatov Institute PNPI)\nThis
  report presents the latest results and analysis strategy for the search f
 or Higgs boson decays into dark matter (DM) particles using data collected
  during Runs 1 and 2 of the Large Hadron Collider (LHC). The search is int
 erpreted within Higgs-portal models\, in which the Higgs boson provides a 
 connection between the Standard Model and the dark sector. Upper limits on
  the Higgs boson branching fraction to invisible final states are derived 
 at a 95% confidence level\, assuming the Standard Model Higgs boson produc
 tion cross section. The obtained limits represent the most stringent const
 raints from the ATLAS and CMS experiments at the LHC to date. These values
  from the ATLAS experiment are compared with the results of direct search 
 experiments.\n\nThe prospects for extending the ATLAS search using data co
 llected during the initial period of LHC Run 3 are also discussed\, with p
 articular emphasis on the expected sensitivity to invisible Higgs boson de
 cays.\n\nhttps://indico.particle.mephi.ru/event/626/contributions/6178/
