We present the recent results from combinations of searches for a standard model (SM) Higgs boson (H) by the CDF and D0 experiments at the Tevatron collider at √s = 1.96 TeV. The data correspond to an integrated total luminosity of 8.2 (CDF) and 8.6 (D0) fb−1. Compared to the previous Tevatron Higgs boson search combination more data have been added, additional channels have been added, and some previously used channels have been reanalyzed to gain sensitivity. No excess is observed above background expectation, and set 95% C.L. upper limits (median expected) on Higgs boson production at factors of 1.17 (1.16), 1.71 (1.16), and 0.48(0.57) times the SM predictions for Higgs bosons of mass mH = 115, 140, and 165 GeV/c2, respectively. We exclude a standard-model Higgs boson in the mass range 156-177 GeV/c2 at the 95% C.L, with an expected exclusion region 148-180 GeV/c2. The absence of a Higgs boson signal also constrains some new physics such as 4th generation models and other exotic models.
