Higgs Boson Results from the Tevatron

Abstract

The CDF and D0 collaborations carried out a vigorous program of searches for the Higgs boson(s) predicted by the standard model and selected extensions. All major production modes were included in the searches: production of Higgs bosons in association with a $W$ or a $Z$ boson, gluon-gluon fusion, vector boson fusion, and production in association with a pair of top quarks. Higgs boson decays to $b{\bar{b}}$, $W^+W^-$, $\tau^+\tau^-$, $ZZ$, and $\gamma\gamma$ were explicitly sought, giving sensitivity for Higgs boson masses between 90 GeV/$c^2$ and 200 GeV/$c^2$. An excess of candidate events in the mass range 115 GeV/$c^2$ -- 140 GeV/$c^2$ is observed. The data from all of the separate search channels are consistent with the expectation for a standard model Higgs boson of mass near 125 GeV/$c^2$, indicated by the recent discovery by the LHC collaborations ATLAS and CMS. Results of searches for a fermiophobic Higgs boson and searches for Higgs bosons in the context of the standard model with a fourth sequential generation of fermions, are also presented.
