Time reversal symmetry has been one of the most intriguing aspects of the tests on discrete symmetries.
So far, Time reversal symmetry violation has not been observed in purely leptonic systems [1].
The most promising experimental upper limits for CP and CPT (C-Charge Conjugation, P-Parity, and T-Time) symmetry violation in positronium decay is set to 0.3$\times10^{-3}$ [2, 3].

The electron-positron annihilation into two photons is a standard technology in medicine to observe e.g. metabolic processes in human bodies. A new tomograph, the J-PET, will provide the possibility to observe not only direct positron-electron annihilations but also the 2-photon and 3-photons decay of positronium atoms. Moreover, the polarisation properties of these photons may become...
Physics at the CERN kaon factory: recent results and prospects for the future
Precise measurements of the branching ratios (BRs) for the flavor-changing neutral current decays KL→πνν can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. It is important to measure both decay modes, K+ → π+νν and KL → π0νν, since different new physics models affect the rates for each channel differently. For the charged channel, the NA62 experiment at the...
Using 1.63 fb−1 of integrated luminosity collected by the KLOE experiment about 7 × 104 KS → π±e∓ν decays have been reconstructed. The measured value of the charge asymmetry for this decay is AS = (−4.9 ± 5.7stat ± 2.6syst) × 10−3, which is almost twice more precise than the previous KLOE result. The combination of these two measure- ments gives AS = (−3.8 ± 5.0stat ± 2.6syst) × 10−3 and,...
KLOE-2 physics program is mainly focused on KS, η and η meson rare decays as well as on kaon interferometry, fundamental symmetry tests and physics beyond the Standard Model, including searches for new exotic particles that could constitute the dark matter. The entanglement in the neutral kaon pairs produced at the DAΦNE φ-factory is a unique tool to test discrete symmetries and quantum...
The latest results obtained by the KLOE experiment at DAFNE, the phi-factory collider in operation at the Laboratori Nazionali di Frascati of INFN, on the the Dalitz plot analysis of the eta->pi+pi-pi0 decay and searches for two pion decays will be presented, together with the status and prospects for the analysis of KLOE-2 data.
