Constraints on CPT violating parameters
Abstract
Neutral kaons provide one of the most sensitive system to CP and CPT violation. Tests on CP, CPT and quantum mechanics have been performed at KLOE operating at the DAFNE e+e- collider. Results on the quantum interference in the channel phi-> KSKL ->pi+pi-pi+pi-, the measurement of the BR(KL ->pi+pi-) and the related CP violating parameter epsilon are presented. Using the Bell-Steinberger relation, CPT violating parameters have been also obtained
