A search for the standard model (SM) Higgs boson (H) decaying to b b
‾ when produced in association with an electroweak vector boson is
reported for the following processes: Z (νν) H, W (μν) H, W
(eν) H, Z (μμ) H, and Z (ee) H. The search is performed in data
samples corresponding to an integrated luminosity of 35.9fb-1
at √{ s } = 13TeV recorded by the CMS experiment at the LHC during
Run 2 in 2016. An excess of events is observed in data compared to the
expectation in the absence of a H → b b ‾ signal. The
significance of this excess is 3.3 standard deviations, where the
expectation from SM Higgs boson production is 2.8. The signal strength
corresponding to this excess, relative to that of the SM Higgs boson
production, is 1.2 ± 0.4. When combined with the Run 1
measurement of the same processes, the signal significance is 3.8
standard deviations with 3.8 expected. The corresponding signal
strength, relative to that of the SM Higgs boson, is
1.06-0.29+0.31.
