摘要：

The positronium system, a bound state of an electron and a positron, is suitable for testing the predictions of quantum electrodynamics (QED) as well as symmetry invariance. The Ps triple state, the ortho-Positronium (o-Ps), which mainly decays to three photons, is further studied to search for decays into 4γ and 5γ, the former C-violating decay and the latter never observed. The J-PET is a multi-purpose detector optimized for the detection of photons from positron–electron annihilation and can be used in a broad scope of interdisciplinary investigation. The large acceptance and high angular resolution of the J-PET detector will push the present limits in these forbidden and rare decays. The aim is to reach a sensitivity below O(10−6) while reducing the uncertainties, thus increasing the sensitivity. © 2024 Jagiellonian University. All rights reserved.
