Krótki opis

The aim of the project is to search for Dark Matter (DM) candidates in the Positronium system. Positronium is a bound state of an electron and a positron, suitable for testing the predictions of quantum electrodynamics (QED). Present positronium experiments search for invisible decays of its triplet state, the ortho-Positronium (o-Ps), which mainly decays to three photons. These invisible decays are sensitive to new physics scenarios, e.g. mirror matter. Mirror matter would interact with normal particles mainly through gravity, thus becoming possible DM candidates.

The aim of this work is to perform feasibility studies of the ortho-Positronium lifetime estimation using a slow beam of positrons. For this, Monte Carlo simulations with dedicated packages will be developed and analyzed.

The JPET is a novel, total-body Positron-Electron Tomograph (PET) scanner, a large and high precise medical imaging tool, based on the plastic scintillators. In the case of the JPET at the Jagiellonian University, a novel PET scanner technology has been developed.
