37. Analysis of CP conserving Higgs bosons self coupligs in SM$\times$S(3)

Dr EZEQUIEL RODRÍGUEZ (UNIVERSIDAD DE SONORA)

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,...

39. Discreteness in parameters of the Standard Model

Dr Sergey Sukhoruchkin (Petersburg Nuclear Physics Institute)

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. 1. Sukhoruchkin, S.: J. Phys.: Conf. Ser. {\bf 381} (2012) 012076; ...

14. Charged Higgs bosons in single top production at the LHC

Renato Guedes

06/12/2012, 17:25

We show that a light charged Higgs boson signal via tau nu decay can be established at the Large Hadron Collider also in the single top mode. This process complements searches for the same signal in the case of charged Higgs bosons emerging from t¯t production. The models accessible include the Minimal Supersymmetric Standard Model (MSSM) as well a variety of 2-Higgs Doublet Models...

35. B -> D(*) tau nu Decays in the 2HDM

Mr Alejandro Celis (IFIC-Universitat de Valencia)

06/12/2012, 17:50

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...

46. Charged Lepton Violation in future linear colliders

Higgs Physics

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.
