The semileptonic decays τ− → μ−M(M = π, η, η′) could be sensitive probe for new physics scenarios with lepton flavor violation(LFV). Motivated by the recent Belle measurement, we investigate these decays in type III two-Higgs-doublet model (2HDM III), R-parity violating supersymmetric models(RPV SUSY) and flavor changing Z′ model, which have LFV couplings at tree level. Our results have shown t...

We perform comparative studies for four types of the two Higgs Doublet Models (2HDMs) under precision measurements Standard Model (SM) observables at proposed factories. explore discovery potential based on hypothetical deviations in data 2HDMs up to one-loop level. find $5\sigma$ observability from $\chi^2$ fitting a significant theory parameter space future For Type-I 2HDM, regions with $\cos...

The ratio of the vacuum expectation value of the two Higgs doublets, tanβ, is an important parameter of the general 2-HiggsDoublet Model (2HDM) and the Minimal Supersymmetric extension of the Standard Model (MSSM). The expected uncertainty on the determination of tanβ at a Linear Collider (LC) of at least 500 GeV center-of-mass energy and high luminosity is reviewed based on studies of neutral ...

We analyze the thermal history of 2HDM and determine parameter regions featuring a first-order electroweak phase transition (FOEWPT) also much less studied phenomena like high-temperature (EW) symmetry non-restoration possibility vacuum trapping (i.e. Universe remains trapped in an EW-symmetric throughout cosmological evolution, despite at $T=0$ EW breaking is deeper). show that presence impede...

In the two-Higgs-doublet model, different Higgs doublets can be viewed as components of a generic ”hyperspinor”. We decompose the Higgs potential of this model into irreducible representations of the SU(2) group of transformations of this hyperspinor. We discuss invariant combinations of Higgs potential parameters λi that arise in this decomposition and provide simple and concise sets of condit...

The mixing induced time dependent CP asymmetry, direct CP asymmetry, and branching ratio in B → ΦK S in a model III 2HDM are calculated, in particular, neutral Higgs boson contributions are included. It is shown that satisfying all the relevant experimental constraints, for time dependent CP asymmetry S φK the model III can agree with the present data, s φ k = −0.39 ± 0.41, within the 1σ error,...

We present the computation of the leading one-loop electroweak radiative corrections to the non-standard top quark decay width Γ(t → H b), using a physically motivated definition of tanβ. We find that the corrections are large, both in the Minimal Supersymmetric Standard Model (MSSM) and the Two-Higgs-Doublet Model (2HDM). These corrections have an important effect on the interpretation of the ...
