17 Oct 2012 | | Abstract: | We study the consistency of two Higgs doublet models in light of the new
bosonic particle discovery at the LHC. We work within a general setup that we
call the 2HDM-X, in which the quarks couple to both scalar doublets with
aligned couplings such that flavor-changing neutral currents are absent at tree
level. The 2HDM-X encompasses the traditional Type I, Type II, lepton specific,
and flipped models, but also provides for more general possibilities. The best
fit to the current data with a suppressed tau tau signal and a b bbar signal of
Standard Model strength is given by the 2HDM-X with specific parameter choices;
however, very good fits are also obtained within the lepton-specific model and
a democratic model, the 2HDM-D, in which both the up-type and down-type quarks
couple to each doublet with equal strengths. The approach provides a general
framework in which to interpret future LHC Higgs data within extensions of the
Standard Model with two Higgs doublets. | | Source: | arXiv, 1210.4922 | | Services: | Forum | Review | PDF | Favorites | |
