Results are consistent with a Standard Model Higgs boson

Supports the Higgs discovery claims from the LHC

Abstract

We present the combination of searches for the Standard Model Higgs boson, using up to 10 \invfb\ of $p\bar p$ collisions at $\sqrts$=1.96 TeV collected with the CDF and \dzero\ 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 $H\to b\bar b$, $H\to\tau^+\tau^-$, $H\to W^+W^-$, and $H\to \gamma\gamma$. 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 $VH \to V b\bar b$ channels.
