👉 The Belle project is an international collaboration aimed at advancing the field of particle physics through the construction and operation of the Belle II experiment at Japan's SuperKEKB accelerator facility. Belle II is designed to study the properties of B mesons, particles that are crucial for understanding CP violation (a phenomenon where matter and antimatter behave differently) and the matter-antimatter asymmetry in the universe. By analyzing rare decays of B mesons, the project seeks to uncover new physics beyond the Standard Model and provide insights into fundamental questions about the universe's composition and evolution.
