چکیده

We present the implications of recent measurement $W$ boson at CDF II on two-Higgs-doublet model (2HDM). In analysis, we impose theoretical bounds such as vacuum stability and perturbative unitarity, several experimental constraints. addition, take into account ${\mathrm{sin}}^{2}{\ensuremath{\theta}}_{W}({m}_{Z}{)}_{\overline{\mathrm{MS}}}$ top $W$-boson mass to investigate how $S$ $T$ parameters are determined. explore two possible scenarios depending whether Higgs observed LHC is lighter or heavier $CP$-even neutral bosons for 2HDM type I II. Using results, show parameter space constrained, compare it with one based PDG average ${m}_{W}$. Furthermore, phenomenological consequences electroweak precision observables that can be affected by ${m}_{W}$ within predictions 2HDM, reduction in expected from future measurements Future Circular Lepton Collider.

Mass Terms in Two-Higgs Doublet Models

We take a closer look at the mass terms of all renormalizable and CP conserving twoHiggs doublet models (THDM). We show how some of the dimension two parameters in the potential can be set equal to zero leading to relations among the tree-level parameters of the potential. The different versions of the THDM obtained give rise to different amplitudes for physical processes. We will illustrate th...

Mass bounds of the lightest CP-even Higgs boson in the two-Higgs-doublet model

The upper and the lower bounds of the lightest CP-even Higgs-boson mass (mh) are discussed in the two-Higgs-doublet model (2HDM) with a softly-broken discrete symmetry. They are obtained as a function of a cut-off scale Λ (≤ 10 GeV) by imposing the conditions in which the running coupling constants neither blow up nor fall down below Λ. In comparison with the standard model (SM), although the u...

Two-higgs-doublet-models and Radiative Cp Violation Two-higgs-doublet-models and Radiative Cp Violation

We discuss the feasibility of spontaneous CP violation being induced by radiative corrections in 2HDM’s. Specifically, we analyze the cases of gaugino/higgsino effect on MSSM, and a new model with an extra exotic quark doublet. The new model, while demonstrating well the Georgi-Pais theorem, is also expected to be phenomenlogically interesting. ————— ⋆ Talk given by O.K. at MRST conference, McG...

On the Renormalization of Two-Higgs-Doublet Models

In this paper we perform the complete one-loop renormalization of a general Two-Higgs-Doublet Model. We present all the vertices for this model including the ones in the scalar sector and calculate all the counterterms of the theory. e-mail:[email protected] Partially supported by JNICT contract BD/2077/92-RM

Vacuum Stability in two-Higgs doublet models

In this work we review the status of tree-level vacuum stability in general two-Higgs doublet models. We also discuss the problem of Normal minima in some classes of potentials. In some of these potentials, Normal minima can coexist leading to potentially dangerous physic scenarios as, for instance, a two step spontaneous symmetry breaking.
