ABSTRACT
We study the inclusion of non-standard soft-breaking terms in the minimal SUSY extension of the SM, considering it as a model of weak-scale SUSY. These terms modify the higgs-sfermion interaction and the sfermion mass matrices, which can induce new sources of flavour violation. Bounds on the new soft parameters can be obtained from current data. The results are then applied to evaluate the FCNC top quark decays t → c + h[sub i] (h[sub i] = h[sup 0], H[sup 0], A[sup 0]). Implications of complex soft parameters for CP-violation are also addressed.

    There are currently two hints for new physics involving CP violation in b → s transitions: ΔS ≡ Sf - SJ/ψK ≠ 0, and difference in direct CP asymmetry ΔAKπ ≡ AK + π0 - AK + π- ≠ 0. We explore the two scenarios with a large and unique new CP...

    It has been pointed out that supersymmetric extensions of the Standard Model can induce significant changes to the theoretical prediction of the ratio Γ( K→ eν)/ Γ( K→ μν)≡ R, through lepton flavour violating couplings. In this work we carry out a full...

    Charged Higgs bosons are predicted in several extensions of the Standard Model, where the Higgs sector contains more than one doublet of complex scalars, for instance in the Minimal Supersymmetric Standard Model (MSSM). For mH+ < mtop, the dominant production mode for charged Higgs bosons at the...

    Most extensions of the Standard Model lepton sector predict large lepton flavor violating rates. Given the promising experimental perspectives for lepton flavor violation in the next few years, this generic expectation might offer a powerful indirect probe to look for new physics. In this review...
