A model for the origin and mechanisms of CP violation
- Department of Physics, Carnegie Mellon University, Pittsburgh, Pennsylvania 15213-3890 (United States)
In this talk I will show that the two-Higgs doublet model with vacuum CP violation and approximate global {ital U}(1) family symmetries may provide one of the simplest and attractive models for understanding the origin and mechanisms of CP violation. It is shown that the mechanism of spontaneous symmetry breaking provides not only a mechanism for generating masses of the bosons and fermions, but also a mechanism for creating CP-phases of the bosons and fermions, so that CP violation occurs, after spontaneous symmetry breaking, in all possible ways from a single CP phase of the vacuum and is generally classified into four types of CP-violating mechanism. A new type of CP-violating mechanism in the charged Higgs boson interactions of the fermions is emphasized and can provide a consistent description for both established and reported CP-, P-, and T-violating phenomena. Of particular importance is the new source of CP violation for charged Higgs boson interactions that lead to the value of {epsilon}{prime}/{epsilon} as large as 10{sup {minus}3} independent of the CKM phase. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
