Tevatron Combination and Higgs Boson Properties

Abstract

We present the Tevatron combination of searches for the Higgs boson and studies of its properties. The searches use up to 10 fb${}^{-1}$ of Tevatron collider Run II data. We observe a significant excess of events in the mass range between 115 and 140 GeV/c${}^2$. The local significance corresponds to 3 Gaussian standard deviations at the mass of 125 GeV/c${}^2$. Furthermore, we separately combine searches for the Higgs boson decaying to $b\bar{b}$, ${\tau }^{+}{\tau }^{-}$, $W^{+}{W}^{-}$, and photon pairs in the final states. The observed signal strengths in all channels are consistent with the presence of a standard model scalar boson with a mass of 125 GeV/c${}^2$. Studies of the couplings at the Tevatron are consistent with SM predictions and are complementary to those performed at LHC.
