The Belle II detector got off to a successful start in Japan. Since March 25, 2019, the instrument has been measuring the first particle collisions, which are generated in the modernized SuperKEKB accelerator. The new duo produces more than 50 times the number of collisions compared to its predecessor. The huge increase in evaluable data means that there is not a greater chance of finding out why there is an imbalance between matter and anti-matter in the Universe.
