Abstract

We present the combination of searches for the Standard Model Higgs boson, using up to 10 fb⁻¹ of $p\overline{p}$ collisions at √s = 1.96 TeV collected with the CDF and D0 detectors at the Fermilab Tevatron collider. The major contributing channels are optimized for the main production modes, the associated production with a vector boson (VH, with V = W, Z), the vector boson fusion, and the gluon-gluon fusion, and the different decay modes $H\to b\overline{b},H\to {\tau }^{\text{+}}{\tau }^{-},H\to W^{\text{+}}{W}^{-}$, and H → γγ. A significant excess of events is observed in the mass range 115 < M_H < 140 GeV. The local significance corresponds to 3.0 standard deviations at m_H = 125 GeV, consistent with the mass of the new particle observed at the LHC. The observed signal strengths in all channels are consistent with the presence of a standard model Higgs boson of mass 125 GeV. We also present prospects for spin/parity tests to be performed in the VH → V$b\overline{b}$ channels.
