On the trail of antimatter

A big question of science is why and where antimatter disappeared after the big bang. Numerous projects around the world are working to answer this question. The T2K experiment is also dedicated to the study of antimatter. Now, analysis of the data obtained during the experiment has revealed signs of differences between matter and antimatter. These differences could be a step towards unravelling the matter-antimatter asymmetry.

The consortium of over 500 experts has now published a groundbreaking discovery that is currently the cover story of the specialist magazine "nature". The scientists have examined data from the past nine years of research and found that there are differences in the behaviour of neutrinos and antineutrinos. This is a violation of mirror symmetry.

Despite the joy about the achieved research success, the scientists are still at the very beginning. For the international research team, this means further work in this area and within the T2K experiment in the coming years. This also applies to Prof. Stefan Roth. With him, a scientist from the JARA-FAME section is also involved in the investigations. Roth is part of the III Physics Institute B, RWTH Aachen University, which is headed by JARA-FAME Director Prof. Achim Stahl.
