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…

First-in-human quantum entanglement imaging

Pawel Moskal, Deepak Kumar, Sushil Sharma +37

Annihilation photons are quantum-entangled in polarization, a phenomenon that has not been exploited in medical diagnostics so far. We present the first in vivo imaging of the degr…
