Belle II Shines with New Upgrades and Exciting Discoveries Ahead

Belle II resumes operations at CERN

After a scheduled long shutdown that began in summer 2022, the Belle II detector at SuperKEKB in Japan recorded its first e+e- collisions on 20 February. During this shutdown, several upgrades were made to the facility to better handle the expected increases in luminosity and backgrounds originating from the beams.

The Belle II experiment aims to uncover new phenomena through precise analysis of the properties of B mesons and other particles produced by the SuperKEKB accelerator. The long-term goal of Belle II is to accumulate a dataset that is 50 times larger than that of the former Belle experiment. This ambitious goal will allow researchers to delve deeper into the mysteries of particle physics and potentially discover new physics beyond the Standard Model.

To achieve these goals, several enhancements were made to the facility during the shutdown. This included installing a new vertex detector with a fully implemented pixel detector and an improved beam pipe at the collision point. Additionally, enhancements were made to the radiation shielding around the detector and other measures were implemented to improve data-collection performance.

Overall, the successful start of Run 2 at Belle II marks an important milestone in the ongoing research efforts at the facility. With
