$\mathcal{C}\mathcal{P}$ Violation from String Theory

Abstract

We identify a natural way to embed $\mathcal{C}\mathcal{P}$ symmetry and its violation in string theory. The $\mathcal{C}\mathcal{P}$ symmetry of the low energy effective theory is broken by the presence of heavy string modes. $\mathcal{C}\mathcal{P}$ violation is the result of an interplay of $\mathcal{C}\mathcal{P}$ and flavor symmetry. $\mathcal{C}\mathcal{P}$ violating decays of the heavy modes could originate a cosmological matter-antimatter asymmetry.
