Infra-red fixed points in supersymmetry

[摘要] Model independent constraints on supersymmetric models emerge when certain couplings are drawn towards their infra-red (quasi) fixed points in the course of their renormalization group evolution. The general principles are first reviewed and the conclusions for some recent studies of theories with 𝑅-parity and baryon and lepton number violations are summarized.
