Abstract: A search for Higgs boson decays to invisible particles, produced in association with a top quark pair or a vector boson decaying in a fully hadronic final state, has been performed using 138 fb−1 of proton-proton collision data collected at √s= 13 TeV by the CMS experiment at the LHC. Events are categorized based on jet multiplicity, the number of jets stemming from b quark decays as well as the number of hadronically decaying boosted top quarks and W bosons reconstructed as a single large-cone jet in the detector. The observed (expected) limit set on the invisible branching fraction of the 125 GeV Higgs boson is 0.47 (0.40), assuming standard model production cross sections. Finally, the results of this analysis are combined with previous CMS measurements of the Higgs to invisible branching fraction carried out at √s= 7, 8, and 13 TeV in complementary production modes. The combined limit on the branching fraction is 0.15 (0.08), the most stringent result from direct searches at CMS to date. | ||

Summary |
A search for invisible decays of Higgs bosons produced in association with top quark pairs (ttH) or vector bosons (VH) is presented. The analysis is based on 138 fb−1 of pp data collected at √s= 13 TeV during the 2016 -- 2018 data taking period by the CMS experiment at the LHC. The ttH production mechanism is investigated using fully hadronic final states with b jets, including event categories with boosted top quark or vector boson candidates. The analysis of VH production focuses on a di-jet pair with an invariant mass that is compatible with that of a W or Z boson. Three types of CRs in data, with one or two leptons, or a photon are used directly in the fit to constrain the main SM backgrounds. In the absence of any significant excess in data, a 95% confidence level observed (expected) upper limit of 0.47 (0.40) is set on the Higgs boson to invisible branching fraction, assuming SM production cross sections. These results are combined with those obtained from Higgs production in vector boson fusion, associated production, gluon-gluon fusion as well as leptonic ttH and ZH decays to obtain an observed (expected) combined upper limit on the Higgs to invisible branching fraction of 0.15 (0.08) at 95% confidence level. |
