Description
A direct test of the T, CP and CPT symmetries in the neutral kaon system can
be performed comparing a transition process i → f to its symmetry
conjugated one. The exchange of in and out states required for genuine tests
involving the time-reversal T can be performed exploiting the entanglement
of the kaon pair produced at a φ-factory. In particular using this method it
would be possible to perform a very clean and fully robust CPT test, which
might shed light on possible new CPT violating mechanisms.
The KLOE-2 experiment at the INFN Laboratori Nazionali di Frascati (LNF) is
currently taking data at the e+e- DAFNE collider, the Frascati φ-factory.
An integrated luminosity of 4.5/fb has been already collected by KLOE-2,
and at least 5/fb are expected by Spring 2018.
The implementation of the CPT test in transitions at KLOE-2 will be
discussed and recent KLOE results on related CP/CPT tests will be
presented.
