Abstract

The KLOE-2 detector records decays of quantum-entangled pairs of neutral kaons produced in decays of phi mesons provided by the DAFNE accelerator at the Laboratori Nazionali di Frascati, Italy. This system allows for a broad range of studies of fundamental discrete symmetries including tests which are only feasible with entangled neutral mesons. This work reports on the Lorentz non-invariance and CPT violation searches with the KSKL->pi+pi-pi+pi- process in the framework of the Standard Model Extension. Moreover, status and results of quantum coherence tests with the same process are discussed. Finally, the status of ongoing direct tests of T and CPT in neutral kaon transitions is presented. For each of thereported studies, perspectives are discussed for the KLOE-2 experiment, which is presently taking data.

Highlights

  • Systems of flavoured neutral mesons have long proven to constitute an excellent ground for studies of the fundamental discrete symmetries of Nature as conservation of the latter can be translated to constraints on the properties of such systems

  • Gajos mechanics as has been shown by the KLOE experiment, which to date is the sole experimental setup where K0K 0 pairs are available in a quantum entangled state, provided by the DAΦNE φ-factory

  • This work reports on the recent tests of both discrete symmetries and quantum coherence performed by KLOE and the perspectives for KLOE-2 results

TESTS OF DISCRETE SYMMETRIES AND QUANTUM COHERENCE WITH NEUTRAL KAONS AT THE KLOE-2 EXPERIMENT∗.
