| Positronium (Ps), an exotic atom composed of an electron and a positron, provides a unique system for testing fundamental physics and verifying quantum electrodynamic predictions. At Jagiellonian University, the J-PET detector enables high-precision studies of positronium decays and the search for dark matter. This work focuses on mirror matter, a hypothetical dark matter candidate, by comparing measured o-Ps lifetimes with quantum electrodynamic predictions to probe potential deviations. |
