„Nature” about matter and antimatter
T2K Results Restrict Possible Values of Neutrino CP Phase – published in “Nature”. The results are a major step forward in the study of the difference between matter and antimatter.
On 15 April 2020 the international team of physicists, carrying out the neutrino experiment T2K (Tokai to Kamioka) in Japan, announced in the prestigious science journal “Nature” the observation of the fundamental difference in behavior of neutrinos and antineutrinos registered in Super-Kamiokande detector.
The observed asymmetry is considered to be essential in explaining the domination of the matter in the universe and it has opened the way for more accurate measurements in the future neutrino accelerator experiments.
Involvement of Polish researchers
T2K experiment is a joint endeavor of about 500 scientist from 12 countries. Poland is represented in it by 6 research teams from: the Institute of Nuclear Physics of the Polish Academy of Sciences, the University of Silesia, National Centre for Nuclear Research, Warsaw University of Technology, the University of Warsaw and the University of Wrocław.
More information about T2K Collaboration, including the press release in English about the article in ”Nature”, is available on the PAS Institute of Nuclear Physics website.
