Xdll in a CP softly broken two Higgs doublet model

We study the differential branching ratio, forward-backward asymmetry, CP-violating asymmetry, CP-violating asymmetry in the forward-backward asymmetry and polarization asymmetries of the final lepton in the B → Xd l+l−decays in the context of a CP softly broken two Higgs doublet model. We analyze the dependencies of these observables on the model parameters by paying a special attention to the...

Simple Two Higgs Doublet Model

Decay in Two Higgs Doublet Model

The rare K + → π + ν ¯ ν decay is investigated in the context of type II two-Higgs-doublet model (2HDM). By using the existing experimental data of the branching ratio, restrictions on the free parameters of the model m H , and tanβ are obtained: 0.7 ≤ tanβ ≤ 0.8, and 500GeV ≤ m H ≤ 700GeV .

Constraints on the two-Higgs-doublet model

The two-Higgs-doublet model provides a simple, yet interesting, generalization of the SM Higgs sector. We study the CP-conserving version of this model with general, flavor-diagonal, Yukawa couplings. Indirect constraints are obtained from flavor physics on the charged Higgs boson mass and couplings. The relation of these bounds to those for the more specialized two-Higgsdoublet model types wit...
