The journal ‘Nature Communications’ has published the result of the world’s most accurate test of the symmetry between matter and antimatter in a positronium atom performed by the J-PET Team led by Professor Paweł Moskal from the Department of Physics, Astronomy and Applied Computer Science at the Jagiellonian University (UJ) in Krakow.
“At the UJ, we designed and built a prototype of the world’s first positron emission tomograph operating with plastic scintillators”, says Prof Paweł Moskal.
The physicist from the Jagiellonian University adds that preliminary tests carried out demonstrate the ability of the prototype to measure the decay of positronium atoms into photons. ‘We have collected the first data and tested the symmetry between matter and antimatter with a precision several times better than that obtained in previous experiments’, states Prof Moskal, who emphasises that the main outcome of the project will be a deeper understanding of matter in the Universe and the electromagnetic interactions responsible for the existence of atoms, molecules and ourselves.
