Is the new CDF M measurement consistent with the two-Higgs doublet model?

In the Two - Higgs Doublet - Model

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...

Simple Two Higgs Doublet Model

First Order Phase Transition in a Two Higgs-doublet Model with M H > M W * Disclaimer

We study the 3d effective field theory of a weakly coupled two Higgs-doublet scalar model at high temperature. Our model has three scalar quartic couplings and an O(4) symmetry which is spontaneously broken by a nonzero scalar field vev at zero temperature. Using high temperature perturbation theory, renormalization group arguments in 4− ǫ dimensions, as well as 1/N expansion techniques in 3 di...

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 .
