Searching for missing anti-matter: A successful start to measurements with Belle II
(PHYSorg.com Physics)

Since March 25, 2019, the Belle II detector instrument in Japan has been measuring collisions of particles generated in the SuperKEKB accelerator. The new duo produces more than 50 times the number of collisions compared to its predecessor. The huge increase in data means that there is now a greater chance of explaining the imbalance between matter and antimatter in the universe.
