Date of Defense 1998-07-08 Availability unrestricted Abstract An alternative approach to the problem of CP-violationis presented. It is based on the possibility of
spontaneous CP-breakdown in models with two Higgs doublets.
General features of the phenomenon such as stability of the
vacuum and the existence of a light axion are discussed.
We investigate the feasibility of spontaneously broken
CP in the minimal supersymmetric models - the MSSM and
NMSSM. The latter is shown to be experimentally viable.
The phenomenological implications of the model such as
CP-violating effects in the kaon systems and a nonzero
neutron electric dipole moment are studied.
