Abstract

AsearchfordecaystoinvisibleparticlesofHiggs bosons produced in association with a top-antitop quark pair or a vector boson, which both decay to a fully hadronic f inal state, has been performed using proton-proton collision data collected at √s = 13TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 138fb−1. The 95% confidence level upper limit set on the branching fraction of the 125GeV Higgs boson to invisible particles, B(H → inv),is 0.54 (0.39 expected), assuming standard model production cross sections. The results of this analysis are combined with previous B(H → inv) searches carried out at √s = 7, 8, and 13TeV in complementary production modes. Thecombinedupperlimitat95%confidence level on B(H → inv) is 0.15 (0.08 expected).
