Experimental determination of the Dalitz plot for positronium decay using the J-PET detection system

Magdalena Skurzok, Steven D. Bass, Kamila Kasperska +37

We present the first measurements of the Dalitz plot for ortho-positronium annihilation to three photons. Our measurements, accurate to about 3% statistical and 2-3% systematic unc…

Studies of CPT symmetry in positronium decays with 192 plastic strip J-PET detector

N. Chug, S. D. Bass, E. Y. Beyene +40

A direct test of the CPT symmetry is performed for the electromagnetic decays of ortho-positronium using the J-PET tomograph. We present the precise measurement of the CPT-sensitiv…

Nanoporosity imaging by positronium lifetime tomography

K. Dulski, E. Beyene, N. Chug +25

Positron Annihilation Lifetime Spectroscopy (PALS) is a well-established non-destructive technique used for nanostructural characterization of porous materials. It is based on the…

Non-maximal entanglement of photons from positron-electron annihilation demonstrated using a novel plastic PET scanner

P. Moskal, D. Kumar, S. Sharma +25

In state-of-the-art Positron Emission Tomography (PET), information about annihilation photon polarization is unavailable. Here, we present a PET scanner built from plastic scintil…

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…

Testing CPT symmetry in ortho-positronium decays with positronium annihilation tomography

Paweł Moskal, Aleksander Gajos, Muhsin Mohammed +35

Charged lepton system symmetry under combined charge, parity, and time-reversal transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic limits, discr…
