Abstract

We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90200GeV/c2 produced in the gluon-gluon fusion, WH, ZH, tt¯H, and vector boson fusion processes, and decaying in the Hbb¯, HW+W, HZZ, Hτ+τ, and Hγγ modes. The data correspond to integrated luminosities of up to 10fb1 and were collected at the Fermilab Tevatron in pp¯ collisions at s=1.96TeV. 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 140GeV/c2. The local significance corresponds to 3.0 standard deviations at mH=125GeV/c2, consistent with the mass of the Higgs boson observed at the LHC, and we expect a local significance of 1.9 standard deviations. We separately combine searches for Hbb¯, HW+W, Hτ+τ, and Hγγ. The observed signal strengths in all channels are consistent with the presence of a standard model Higgs boson with a mass of 125GeV/c2.
