Intermediate Vector Mesons and CP-Violations

Abstract

The weak interactions have provided many surprises, the first of which was the violations of the parity (P) and the charge conjugation (C) invariance and, more recently, the CP-violation. The so-called V-A theory proposed by many authors is a very elegant theory which states that the P and C violations occur maximally, so to speak. However, recently discovered violation of the CP (or time-reversal invariance by TCP theorem) is more puzzling, since its effect appears to be very small by a factor of 10^-3 in comparison with the CP-conserving one. To explain this, some authors have suggested to give up the V-A theory by inserting a tiny relative phase-factor between V and A parts. But this is not only artificial but also spoils the beauty of the original V-A theory. Another possibility is simply to assume the existence of a weaker CP- violating interactions, which is again a rather an artificial way without really explaining the reason for its smallness. Here, I would like to propose a new scheme where the CP-violation is maximal as well as maximal violations of separate P and C invariances. At a first glance, this may appear to be quite impossible since experimental CP-violation is smaller by a factor 10^-3 as has been mentioned already. But fortunately, we could make a consistent theory of this kind as will be explained below.
