CP violation in decays into states with neutral kaons

Key Points

The phenomenon of cp violation can significantly affect decay rates in neutral kaon systems, impacting experimental outcomes.
Key metrics include the efficiency function that captures kaon energy spectrum and detector influences, aiding in accurate predictions.
Matter effects on kaon oscillations play a crucial role in determining cp asymmetries, crucial for experimental validation.
Theoretical predictions for cp asymmetries have been estimated, particularly relevant for future Belle II-type experiments.

Abstract

CP violation in the kaon system can manifest itself in decays to final states containing neutral kaons. The effect is governed by an efficiency function that reflects the specific experimental setup. We demonstrate that this efficiency function factorizes into two components: the kaon energy spectrum and a universal detector-dependent factor. We show that matter effects on kaon oscillations can have a significant effect on CP asymmetries. We provide estimates of the theoretical prediction for some such CP asymmetries for a Belle II-type experiment.
