Observation of Higgs Boson Decay to Bottom Quarks

A. M. Sirunyan, A. Tumasyan and W. Adam

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.

Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC

G. Aad

The ATLAS Collaboration reported the observation of a new neutral boson in searches for the Standard Model Higgs boson, using proton-proton collision data from the LHC corresponding to about 4.8 fb⁻¹ at √s = 7 TeV (2011) and 5.8 fb⁻¹ at √s = 8 TeV (2012). Combining sensitive decay channels, the analysis found an excess at a mass of about 126.0 GeV with a local significance of 5.9 standard deviations, consistent with the production and decay of a Standard Model Higgs boson. The result, announced jointly with a companion CMS measurement, provided experimental confirmation of the boson associated with the Brout–Englert–Higgs mechanism of electroweak symmetry breaking.
