Abstract
A search for decays to invisible particles of Higgs
bosons produced in association with a top-antitop quark pair
or a vector boson, which both decay to a fully hadronic
final state, has been performed using proton-proton colli sion data collected at √s = 13 TeV by the CMS experiment
at the LHC, corresponding to an integrated luminosity of
138 fb−1. The 95% confidence level upper limit set on the
branching fraction of the 125 GeV Higgs boson to invisi ble 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 13 TeV in complementary pro duction modes. The combined upper limit at 95% confidence
level on B(H → inv) is 0.15 (0.08 expected).A search for decays to invisible particles of Higgs
