This working group combines CDF and DØ results on
searches for New Phenomena and Higgs bosons on behalf of the collaborations.
Most Recent Spin and Parity Results
April 2015: Combined CDF and DØ Constraints on Models for the Higgs Boson with Exotic Spin and Parity
This is available as T. Aaltonen et al. (CDF and
D0 Collaborations), Phys Rev. Lett. 114, 151802 (2015). The preprint is available at
arXiv:1502.00967 [hep-ex].
CDF and DØ searched for exotic
pseudoscalar and graviton-like Higgs bosons with J P=0- and
2+, respectively, using the VH→Vbb channels.
Limits are set on the production rate times the decay branching rato to bb,
and hypothesis tests are performed and described.
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.
