Physical Quantities

We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero-mode profile. We observe that the numerical values of the physical quantities studied enhance with the additional effects due to the extra dimensions and they are sensitive to the new Higgs localization.

Concentrating on the impact of the very recent top quark discovery, we perform a combined analysis of two strongest constraints on the two-Higgs doublet model, one coming from the recent measurement by CLEO on the inclusive branching ratio of b→sγ decay and the other from the recent LEP data on [Formula: see text] decay. We have included the model predictions for one-loop vertex corrections to [Formula: see text] through εb. We find that the εb constraint excludes most of the less appealing window: tan β≲1 at 95% C.L. for the measured top mass mt=176±8±10 GeV from CDF. Moreover, it excludes tan β≲2 at 95% C.L. for mt≳176 GeV; combined with the b→sγ constraint, only very heavy charged Higgs (≳670 GeV) is allowed by the measured mt from CDF.

The D0 experiment has reported a direct search for a charged Higgs boson produced by [Formula: see text] annihilation and decaying to [Formula: see text] final state, in the 180≤MH+≤300 GeV mass range. The analysis has led to upper limits on the production cross-section in the framework of the two-Higgs doublet model types I, II and III. We compare the predictions of two different scenarios in the framework of the two-Higgs doublet type III to the cross-section limits reported by D0 collaboration, and we obtain constraints on the charged Higgs mass, for the case when the charged Higgs mass is bigger than the top quark mass. Also, searches for the charged Higgs boson with a mass smaller than top quark mass are considered, we discuss the possible limits on the charged Higgs boson mass obtained from measurements of the ratio [Formula: see text] within the two-Higgs doublet model type III.
