Signatures of Extra Dimensions from Upsilon Decays with a Light Gaugephobic Higgs Boson | | Jamison Galloway

16 Jul 2008 | | Abstract: | We explore non-standard Higgs phenomenology in the Gaugephobic Higgs model in
which the Higgs can be lighter than the usually quoted current experimental
bound. The Higgs propagates in the bulk of a 5D space-time and Electroweak
Symmetry Breaking occurs by a combination of boundary conditions in the extra
dimension and an elementary Higgs. The Higgs can thus have a significantly
suppressed coupling to the other Standard Model fields. A large enough
suppression can be found to escape all limits and allow for a Higgs of any
mass, which would be associated with the discovery of W’ and Z’ Kaluza-Klein
resonances at the LHC. The Higgs can be precisely discovered at B-factories
while the LHC would be insensitive to it due to high backgrounds. In this
letter we study the Higgs discovery mode in Upsilon(3S), Upsilon(2S), and
Upsilon(1S) decays, and the model parameter space that will be probed by BaBar,
Belle, and CLEO data. In the absence of an early discovery of a heavy Higgs at
the LHC, A Super-B factory would be an excellent option to further probe this
region. | | Source: | arXiv, 0807.2657 | | Services: | Forum | Review | PDF | Favorites | |
