We combine searches by the CDF and D0 Collaborations for
the associated production of a Higgs boson with a W or Z boson and
subsequent decay of the Higgs boson to a bottom-antibottom quark
pair. The data, originating from Fermilab Tevatron pp̅ collisions
at √s=1.96 TeV, correspond to integrated luminosities of up to
9.7 fb-1. The searches are conducted for a Higgs boson with mass in
the range 100–150 GeV/c2. We observe an excess of events in the
data compared with the background predictions, which is most significant
in the mass range between 120 and 135 GeV/c2. The largest local
significance is 3.3 standard deviations, corresponding to a global
significance of 3.1 standard deviations. We interpret this as evidence
for the presence of a new particle consistent with the standard model
Higgs boson, which is produced in association with a weak vector boson
and decays to a bottom-antibottom quark pair.
