Observation of Higgs Boson Decay to Bottom Quarks
The CMS Collaboration at the CERN LHC reported the observation of the Standard Model Higgs boson decaying to a pair of bottom quarks, the dominant predicted decay channel. The analysis focused on Higgs bosons produced in association with a W or Z boson (VH) in 13 TeV proton-proton collision data from 2017. Combined with earlier 7, 8, and 13 TeV measurements, the result yielded an excess at 125 GeV exceeding 5 standard deviations, establishing the decay.
