Abstract

We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV/c^2 produced in the gluon-gluon fusion, WH, ZH, ttbarH, and vector boson fusion processes, and decaying in the H->bbbar, H->W^+W^-, H->ZZ, H->\tau^+\tau^-, and H->\gamma \gamma\ modes. The data correspond to integrated luminosities of up to 10 fb^-1 and were collected at the Fermilab Tevatron in ppbar collisions at sqrt(s)=1.96 TeV. The searches are also interpreted in the context of fermiophobic and fourth generation models. We observe a significant excess of events in the mass range between 115 and 140 GeV/c^2. The local significance corresponds to 3.1 standard deviations at m_H=125 GeV/c^2, consistent with the mass of the Higgs boson observed at the LHC. Furthermore, we separately combine searches for H->bbbar, H->W^+W^-, H->\tau^+\tau^-, and H->\gamma \gamma. The observed signal strengths in all channels are consistent with the presence of a standard model Higgs boson with a mass of 125 GeV/c^2.
