Background enhancement of $\text{CPT}$ reach at an asymmetric $\phi$ factory

Abstract

Photoproduction of neutral-kaon pairs is studied from the perspective of $\text{CP}$ and $\text{CPT}$ studies. Interference of the $\text{P}$- and $\text{S}$-waves, with the former due to diffractive $\phi$ production and the latter to $f_{0}/a_{0}$ production, is shown to enhance the $\text{CPT}$ reach. Results are presented of Monte Carlo studies based on rates expected in future experiments.
