CPT, Strings, and the $K \bar K$ System

TL;DR

This paper reviews theoretical work on CPT symmetry in string theories, exploring the possibility of observable CPT violation in the kaon system and estimating relevant parameter values for future experiments.

Contribution

It provides a theoretical framework for dynamical and spontaneous CPT violation in string theories and estimates potential CPT violation levels in the kaon system.

Findings

Potential CPT violation levels in the kaon system estimated

Stringy CPT violation could be detectable in upcoming experiments

Theoretical models suggest observable effects at next-generation experimental sensitivities

Abstract

This talk contains a summary of our work on dynamical CPT invariance and spontaneous CPT violation in string theories, including the possibility that stringy CPT violation could occur at levels detectable in the next generation of experiments. In particular, we present here an estimate for values of parameters for CPT violation in the kaon system.
