The Belle II Project

Belle II实验将在位于日本筑波的KEK实验室的SuperKEKB e+e对撞机上进行。它是成功的Belle和BaBar实验的继任者，这两个实验因其对CP违反现象的贡献而被引用于2008年物理学诺贝尔奖。Belle II的主要物理目标是通过广泛的测量来寻找新物理的证据，这些测量对重虚拟粒子的存在很敏感，并且可以在标准模型中精确预测。这些测量可能包括CP破坏和其他不对称、罕见衰变或禁止衰变。这些测量的质量范围可以超过ATLAS和CMS的直接搜索。如果在大型强子对撞机上发现了新的物理现象，Belle II可以通过寻找偏离标准模型的模式来探索它的本质。

The Belle II experiment will be located at the SuperKEKB e+e- collider at the KEK laboratory in Tsukuba, Japan. It is a successor to the successful Belle and BaBar experiments, which were cited for their contributions to the phenomenon of CP violation in the 2008 Physics Nobel Prize. The primary physics goal of Belle II is to search for evidence of new physics through a wide range of measurements that are sensitive to the presence of heavy virtual particles, and that can be precisely predicted in the Standard Model. These measurements could include CP violation and other asymmetries, rare decays, or forbidden decays. The mass reach of these measurements can exceed that of the direct searches by ATLAS and CMS. If new physics is found at the LHC, Belle II can explore its nature by looking for a pattern of deviations from the Standard Model.
