Review of Physics Results from the Tevatron: Higgs Boson Physics

We review the techniques and results of the searches for the Higgs boson performed by the two Tevatron collaborations, CDF and DO. The Higgs boson predicted by the Standard Model was sought in the mass range 90 GeV$<m_H<200$ GeV in all main production modes at the Tevatron: gluon-gluon fusion, $WH$ and $ZH$ associated production, vector boson fusion, and $t\bar{t}H$ production, and in five main decay modes: $H\rightarrow b{\bar{b}}$, $H\rightarrow τ^+τ^-$, $H\rightarrow WW^{(*)}$, $H\rightarrow ZZ^{(*)}$, and $H\rightarrowγγ$. An excess of events was seen in the $H\rightarrow b{\bar{b}}$ searches consistent with a Standard Model Higgs boson with a mass in the range 115 GeV$<m_H<$135 GeV. Assuming a Higgs boson mass of $m_H=125$ GeV, studies of Higgs boson properties were performed, including measurements of the product of the cross section times branching the ratio in various production and decay modes, constraints on Higgs boson couplings to fermions and vector bosons, and tests of spin and parity. We also summarize the results of searches for supersymmetric Higgs bosons, and Higgs bosons in other extensions of the Standard Model.
