Revolutionizing Particle Physics: Belle II Upgrades Prepare for Run 2

Belle II resumes operations at CERN

In the summer of 2022, Belle II detector at SuperKEKB in Japan underwent a long shutdown that aimed to improve its performance and capabilities. During this time, several upgrades were made to the facility, including the installation of 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.

The Belle II experiment first recorded collisions in March 2019 and 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.

Now that Run 2 has begun at Belle II, researchers are poised to collect high-quality data that could lead to exciting discoveries in the field of particle physics. The upgraded detector and improved performance measures in place will help them achieve their goals more efficiently and effectively than ever before. Overall, this important milestone marks an ongoing research effort at SuperKEKB that has the potential to revolutionize our understanding of particle physics for years to come.
