Abstract:

Supersymmetry is undoubtedly a popular candidate for physics beyond the Standard Model. However, the origin of soft supersymmetry breaking masses has been usually depicted intricately in the literature via extra hidden/mediating sectors. Thus, a simple theory for the generation of the soft masses would be more compelling. In this talk, I will present the prototype model with a four-superfield interaction term that induces a real two-superfield composite with vacuum condensate. The latter has supersymmetry breaking parts, which we show to bear nontrivial solution following a standard nonperturbative analysis for a Nambu–Jona-Lasinio type model. No other messenger sector, or hidden sector is needed. Moreover, the analysis of effective theory picture, and the presence of the expected Goldstino along with the supersymmetry breaking, will be also discussed.
