Updated Combination of CDF and DØ's Searches for Standard Model Higgs Boson Production with up to 10.0 fb-1 of Data

June 2012

Preliminary Results

95% C.L. exclusion for SM Higgs with mass mH between 147 and 180 GeV/c2, and between 100 and 103 GeV/c2.

An excess with a significance of 2.5σ is seen that might be interpreted as coming from a Higgs boson with a mass in the region of 115 to 135 GeV. An excess with a significance of 2.9σ is seen in the combination of CDF and DØ's H→bb channels.

The results of combinations of searches for H→bb, H→W+W-, and H→γγ are shown as well.

Documentation: arXiv:1207.0449 [hep-ex]

The same note is available as CDF Note 10884 and DØ Note 6348, and FERMILAB-CONF-12-318-E

Presentations given at Fermilab on July 2: Eric James (CDF) and Wade Fisher (DØ)
