چکیده
We discuss a class of models in which CP is violated softly in a heavy sector adjoined to the standard model. Heavy-sector loops produce the observed CP violation in kaon physics, thus yielding a tiny and probably undetectable value for ǫ. All other CPviolating parameters in the effective low-energy standard model, including the area of the unitarity triangle and θ, are finite, calculable and can be made very small. These models offer a natural realization of superweak CP violation and can resolve the strong CP puzzle. Research supported in part by the National Science Foundation under grant PHY-9218167.

The salient features of CP-violating interactions in the standard elec-troweak theory and in a few of its popular extensions are discussed. Moreover a brief overview is given on the status and prospects of searches for CP non-conservation effects in low and high energy experiments.

We propose a new mechanism called " real CP violation " to originate spontaneous CP violation. Starting with a CP conserving theory with scalar fields in the adjoint representation of a global or local non-abelian symmetry, we show that even though the VEV's of such scalars are real they give rise to a spontaneous violation of CP. We provide an illustrative example of how this new mechanism of ...
