Natural CP Violation Criteria for the Minimal Supersymmetric Standard Model
Robert Garisto
Abstract
CP violating effects in the Minimal Supersymmetric Standard Model (MSSM) can lead to excessively large contributions to the neutron EDM (). We write criteria which ensure that the low energy supergravity (SUGRA) parametrization of the MSSM does not require fine-tunings or large mass scales to evade the constraint from , and consider the implications on SUGRA theories. In particular, we show that in the Polonyi model, two of the mass scales are in general complex, meaning that model does not naturally avoid a large \ as is sometimes claimed.
