CP Violation from a Higher Dimensional Model

TL;DR

This paper demonstrates that a higher-dimensional Randall-Sundrum model naturally introduces CP-violating effects through EDM terms, with analysis of chiral properties, localization, anomalies, and quantum effects.

Contribution

It reveals a novel origin of CP-violation in higher-dimensional models by analyzing the Randall-Sundrum framework and comparing it with Kaluza-Klein theory.

Findings

Randall-Sundrum model contains EDM terms violating CP-symmetry

Chiral properties, localization, and anomalies are examined in the model

Quantum effects induce a new source of CP-violation

Abstract

It is shown that Randall-Sundrum model has the EDM term which violates the CP-symmetry. The comparison with the case of Kaluza-Klein theory is done. The chiral property, localization, anomaly phenomena are examined. We evaluate the bulk quantum effect using the method of the induced effective action. This is a new origin of the CP-violation.
