This working group combines CDF and DØ results on searches for New Phenomena and Higgs bosons on behalf of the collaborations.

Most Recent SM Higgs Search Results

Spring/Summer 2013: Higgs Boson Studies at the Tevatron with 10 fb-1 of data This is available as Phys. Rev. D 88, 052014 (2013). The preprint is available at arXiv:1303.6346. This paper documents searches for the SM Higgs boson and studies of the excess of events collected by CDF and DØ Results are reported for the SM Higgs boson, the Higgs boson of the SM4, and also for a Fermiophobic Higgs model. Coupling fits are performed and described.

Summer 2012 Combined CDF and DØ Searches for H→bb in associated production channels Evidence for a particle produced in association with a weak vector boson and which decays to a bottom-antibottom pair. Published in the August 17, 2012 issue of Physical Review Letters.

Summer 2012 Combined CDF and DØ Searches for Standard Model Higgs Boson Production, with Luminosities up to 10 fb-1 Preliminary Results. 95% C.L. exclusion of 147 < mH < 180 GeV/c2. A 2.5σ excess is seen that might be interpreted as coming from a Higgs boson with a mass in the region of 115 to 135 GeV. Searches for H→bb, H→W+W-, and H→γγ are combined. A 2.9σ excess is seen in the combined H→bb searches.

Most Recent b-Tagged WZ/ZZ Measurement

Winter 2012 Combined CDF and DØ Measurement of WZ and ZZ Production in b-tagged Final States with up to 9.5 fb-1 of Data Preliminary results. Validation of SM Higgs boson search techniques in the same datasets and analysis techniques.

Most Recent 4th Generation Higgs Search Results

Summer 2011 Combined CDF and DØ upper limits on ggHW+W- and Constraints on Fourth-Generation Fermion Models with up to 8.2 fb-1 of data. Assuming a heavy sequential fourth generation of fermions, 95% C.L. exclusion for a Higgs boson with mass mH between 124 and 286 GeV/c2.

Most Recent Fermiophobic Higgs Search Results

Summer 2011 Combined CDF and DØ upper limits on Fermiophobic Higgs Boson Production with up to 8.2 fb-1. Preliminary Results. 95% C.L. exclusion of mH,Fermiophobic < 119 GeV/c2.

Most Recent MSSM Higgs Search Results

July 2012 Combined CDF and DØ upper limits on neutral Higgs boson production in events with multiple bottom quarks L=2.6fb-1 (CDF) and 5.2 fb-1 (DØ). Submitted to Phys. Rev. D. Rapid Communications.
