An Unusual Two Higgs Doublet Model from Warped Space
arXiv:1004.2953 · doi:10.1103/PhysRevD.82.115022
Abstract
We study a simple two Higgs doublet model (2HDM) in the Randall-Sundrum scenario, with an IR brane localized Higgs field and a second doublet arising from a condensate due to strong Kaluza-Klein gluon effects. The effective 2HDM predicts that the ratio of the brane to condensate vacuum expectation values . It also predicts a standard model like Higgs boson of mass GeV and a heavier scalar at the scale of the lowest KK gluon mass, which we take to be TeV. The pseudoscalar and the charged scalars are degenerate in mass at tree-level and are . There are no tree-level flavor changing neutral currents (FCNC) for the down-type quarks and the standard model results hold there. In contrast, FCNC decays of the t-quark larger than in the SM are expected.
