The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for in final states including 0, 1, or 2 charged leptons and two identified bottom quark jets. The results from the measurement of these processes in a data sample recorded by the CMS experiment in 2017, comprising 41.3??fb?1 of proton-proton collisions at ?s=13??TeV, are described. When combined with previous VH measurements using data collected at ?s=7, 8, and 13 TeV, an excess of events is observed at mH=125??GeV with a significance of 4.8 standard deviations, where the expectation for the SM Higgs boson is 4.9. The corresponding measured signal strength is 1.01±0.22. The combination of this result with searches by the CMS experiment for H?b¯b in other production processes yields an observed (expected) significance of 5.6 (5.5) standard deviations and a signal strength of 1.04±0.20.enParticle decaysBottom quarkHadron collidersArticle10.1103/PhysRevLett.121.1218012-s2.0-8505403607730296133Q1WOS:000444780900004Q1
