Abstract
The long history of kaon physics results produced by KLOE is being continued at the upgraded KLOE-2 detector. Entangled neutral kaon pairs produced at DAΦNE are a unique tool to probe discrete symmetries and QM basic principles at the utmost precision. The status of the newest ongoing analyses using the most refined analysis tools will be presented and discussed:(i) search for decoherence and CPT violation effects in the φ → KSKL → π+ π− π+ π− decay,(ii) test of CP and CPT symmetries in KS semileptonic decays,(iii) test of time reversal and CPT in transitions in φ → KSKL → πeν, 3π0, 2π decays,(iv) study of the KS → π+ π− π0 decay.
