We investigate the CP violation effects in supersymmetry broken models, due to the exchange of new fermions (gauginos and higgsinos). When the real part of the K0 - K0 amplitude is compatible with the experimental value, the possible imaginary part is too small to account for the ε{lunate} parameter. In contrast, the experimental bounds on the ε{lunate}′ parameter and the electric dipole moments, and especially the θ parameter, impose in general severe constraints on the possible CP violating phases. However, in some specific models there are extra suppression factors, leaving those phases essentially unconstrained except perhaps for the θ parameter. © 1983.
