- Аннотация: Extensions of the standard model (SM hereinafter) is a natural way to resolve some issues, which cannot be fully dealt with in the theoretical framework of the conventional high energy physics. In these proceedings the minimal supersymmetric standard model (MSSM) is considered through its applications to mixing processes and rare decays in neutral mesons’ systems with a special emphasis put on the former. Selected results of symbolical calculations and their numerical simulations for a CP violating (non-direct) parameter ε and a mass splitting value ∆mLS in K 0 -, B0 - and D0 -meson systems, d,s due to charged Higgs and chargino exchanges, are presented. The aforementioned results are shown to constrain MSSM scenario-defining parameters (m± and tgβ ) helping to exclude certain H regions at the MSSM plane of parameters (namely for low values of tgβ < 4 and for high values of tgβ > 35 with light charged scalars mH ± < 150GeV ). Prospects of future calculations for rare decays are mentioned as well.
