The 95% confidence level upper limit set on the branching fraction of the 125 GeV 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 root s = 7, 8, and 13 TeV in complementary production modes. The combined upper limit at 95% confidence level on B(H -> inv) is 0.15 (0.08 expected).eninfo:eu-repo/semantics/openAccessArticle10.1140/epjc/s10052-023-11952-78310N/AWOS:0010996325000012-s2.0-8517458276037855556Q1
