B工厂和低能实验对暗力量的限制

Constraints on dark forces from the B factories and low-energy experiments

Abner Soffer

摘要:

暗物质与标准模型粒子的相互作用可能是由质量在MeV到GeV范围内的新玻色子介导的,这一想法在几年前就开始了。对这些模型的约束很快就根据较早的测量计算出来。随后,积极的合作对这些玻色子进行了专门的搜索,并计划进行新的实验以提高搜索灵敏度。在这篇笔记中,我简要介绍了在这个质量范围内预测暗矢量和标量的基本模型,回顾了正负电子对撞机,固定靶实验和强子对撞机的限制,并评论了未来实验的敏感性。

英文摘要:

The idea that dark-matter interactions with Standard-Model particles may be mediated by new bosons with masses in the MeV-to-GeV range took off several years ago. Constraints on such models were soon calculated based on older measurements. Subsequently, active collaborations conducted dedicated searches for these bosons, and new experiments were planned to improve the search sensitivity. In this note I briefly cover the basic models that predict dark vectors and scalars in this mass range, review the constraints from electron-positron colliders, fixed-target experiments, and hadron colliders, and comment on the sensitivities of future experiments.
