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...

The Two Higgs Doublet Model of Type II facing flavour physics data

We discuss tests of the charged Higgs sector of the Two Higgs Doublet Model (2HDM) of Type II in the light of recent flavour physics data. Particular attention is paid to recent measurement of purely leptonic decays of heavy-light mesons, which depart more or less significantly from the Standard Model (SM) predictions. We derive constraints on the parameters of the 2HDM type II from leptonic an...

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 .
