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[superscript 2] produced in the gluon-gluon fusion, WH, ZH, t[¯ over t]H, and vector boson fusion processes, and decaying in the H → b[¯ over b], H → W[superscript +]W[superscript −], H → ZZ, H → τ[superscript +]τ[superscript −], and H → γγ modes. The data correspond to integrated luminosities of up to 10 fb[superscript −1] and were collected at the Fermilab Tevatron in p[¯ over p] collisions at 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[superscript 2]. The local significance corresponds to 3.0 standard deviations at m[subscript H] = 125 GeV/c[superscript 2], 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 H → b[¯ over b], H → W[superscript +]W[superscript −], H → τ[superscript +]τ[superscript −], and H → γγ. 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[superscript 2].
