摘要
CP violating phenomena predicted by the minimal supersymmetric standard model are discussed in a case where the CP violating phases in SUSY sector are not suppressed. The electric dipole moments of the neutron and the electron are large, but can be smaller than their experimental upper bounds if the scalar quarks and leptons are heavier than a few TeV. T violating asymmetries in the production processes of the different neutralino pair and the different chargino pair emerge at the tree level. They could be as large as of order 10(-2) in unpolarized electron beam experiments and 10(-1) in polarized electron beam experiments. In a pair production of the charginos, of the same mass, the asymmetry emerges through the electric and the weak ''electric'' dipole moments of the charginos at the loop level, but its magnitude is at most of order 10(-4).
