In the present paper we show that the Temporal Wave Function approach of thedecay process, which is a multicomponent version of the Time Operator approachleads to new, non-standard, predictions concerning the statistical propertiesof decay time distributions of single kaons and entangled pairs of mesons.These results suggest crucial experimental tests for the existence of a TimeOperator for the decay process to be realized in High Energy Physics or QuantumOptics.
