| contents | 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. |
