Ortho-Positronium Three-Photon Decays: Physics Constraints and a Closed-Form Energy Method for Annihilation Vertex Reconstruction

L. Raczyński, W. Krzemień, A. Coussat +5

We examine the physical foundations of orthopositronium three-photon decay in the context of annihilation vertex reconstruction, focusing on how energy-momentum conservation constr…

Discrete symmetries tested at 10−4 precision using linear polarization of photons from positronium annihilations

Paweł Moskal, Eryk Czerwiński, Juhi Raj +38

Discrete symmetries play an important role in particle physics with violation of CP connected to the matter-antimatter imbalance in the Universe. We report the most precise test of…
