We carry out a detailed analysis of a minimal $S_3$-invariant extension of the Standard Model, with an extended $S_3$-Higgs sector. Within this extended $S(3)$-Standard Model, we study the trilinear Higgs couplings and its dependence on the details of the model, even when the lightest Higgs boson mass is taken to be a fixed parameter. We study quantitatively the trilinear Higgs couplings,...

According to Y. Nambu the existing relations in particle masses can be used for
the development of the Standard Model. We continue the analysis of this
possibility described in the recent publications [1,2]. We show that empirical
relations in the masses of pions (m_{\pi^\pm}, f_{\pi}) can be used in such
analysis.

We analyze the recent experimental evidence for an excess of $\tau$-lepton production in several exclusive semileptonic $B$-meson decays in the context of two-Higgs-doublet models. These decay modes are sensitive to the exchange of charged scalars and constrain strongly their Yukawa interactions. While the usual Type-II scenario cannot accommodate the recent BaBar data, this is possible within...

We investigate the prospects for detection of lepton flavour violation (LFV) in sparticle production and decays at a Linear Collider (LC). We study the Constrained Minimal Supersymmetric extension of the Standard Model (CMSSM) with see-saw neutrinos and use models that fit the latest neutrino data to evaluate signals of LFV on sleptons.
