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…
