摘要
用极化电子束升级SuperKEKB正负电子对撞机，在10.58 GeV质心能量下开启了一项精密物理研究的新计划。本白皮书描述了这一“手性Belle(Chiral Belle)”计划的物理潜力。它包括对的精密测量预期，这些测量可通过对电子、缪子、陶子、粲夸克和b夸克对的跃迁的独立左右不对称性测量获得。SuperKEKB可获得的精度将与LEP/SLC世界平均值相当，但质心能量为10.58 GeV。对缪子、粲夸克和夸克耦合的测量将大幅改进，并将解决SLC的与LEP的测量之间现有的差异。中性流普适性的精密测量将比现有结果精确一个数量级以上。由于能量尺度远离极点，该精密测量将对宇称破缺暗 sector 规范玻色子的存在敏感。该计划还能够以空前精度测量的反常磁矩形状因子。在40~ab数据量下可达到精度，更多数据将开始接近水平。该技术将从第三代粒子提供关于缪子 反常潜在新物理解释的最精确信息。本白皮书还讨论了拥有极化电子束所启用或增强的额外与QCD物理计划。本文包含实现此升级并发挥其令人振奋的发现潜力所需研发路径与后续步骤的总结。
