Evidence for a particle produced in association with weak bosons and decaying to a bottom-antibottom quark pair in Standard Model Higgs search at the Tevatron.

<!--HTML-->We combine results from the CDF and D0 Collaborations on direct searches for the standard model (SM) Higgs boson (H) in ppbar collisions at the Fermilab Tevatron, using 10 fb-1 of data. Searches are carried out for Higgs boson masses between 100 and 200 GeV. There is a significant excess of data events with respect to the background estimation in the mass range 115 &lt; mH&nbsp; &lt; 135 GeV, consistent with the Higgs-like particle recently observed by ATLAS and CMS.<br /> At mH = 120 GeV, the p-value for a background fluctuation to produce this excess corresponds to a local (global) significance of 3.0 (2.5) standard deviations. We also combine separately searches for H--&gt; bb and H --&gt; WW. We find that the excess is concentrated in the H --&gt; bb channel, appearing in the searches over a broad range of mH, as expected from the bb resolution in our detectors. The excess is most significant in the mass range between 120 and 135 GeV.&nbsp; The largest local significance is&nbsp; 3.3 standard deviations, corresponding&nbsp; to a global significance of 3.1 standard deviations. We interpret this as evidence for the presence of a new particle consistent with&nbsp; the standard model Higgs boson, which is produced in association with a weak vector boson and decays to a bottom-antibottom quark pair.
