Breakthroughs Await: Belle II Resumes Data Collection After Major Upgrades

Belle II resumes operations at CERN

The Belle II experiment at SuperKEKB in Japan is now ready to start collecting data after a long shutdown that began in summer 2022. During this time, several upgrades were made to the facility to better handle the expected increases in luminosity and backgrounds originating from the beams.

One of the major upgrades was the installation of a new vertex detector with a fully implemented pixel detector and an improved beam pipe at the collision point. This will allow researchers to collect more precise data on the properties of B mesons and other particles produced by the SuperKEKB accelerator. 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 the fully instrumented detector in March 2019 and aims to uncover new phenomena through precise analysis of these particles. 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.

Overall, this successful start of Run 2 at Belle II marks an important milestone in ongoing research efforts at the facility. With an upgraded detector and improved performance measures in place, researchers are now poised to collect high-quality data that could lead to exciting discoveries in particle physics.
