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…
New limits on CPT-Symmetry Violation in Charm mesons
W. Krzemien, M . Kmiec, A. Szabelski +1
Neutral flavour meson oscillations are a fascinating quantum phenomenon that allows for high-precision tests of fundamental symmetries, including CPT invariance. In this contributi…
New constraints on CPT symmetry violation in charm mesons
Wojciech Krzemien, Mateusz Kmiec, Adam Szabelski +1
Small CPT-violating effects are admissible in several theories beyond the Standard Model of interactions. We analyse experimental data obtained with neutral flavoured meson mixing…
Discrete symmetries tested at 10 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…
