New fundamental particles at the mass scale of a few TeV c^–2 could account for observed phenomena that cannot be explained by the standard model (SM) of particle physics, including the microscopic origin of dark matter and the macroscopic imbalance of matter over antimatter in the Universe. However, no beyond-the-SM (BSM) particles at the TeV scale have yet been detected at the Large Hadron Collider (LHC). With recent innovations, searches for time-reversal symmetry (T) violation through low-energy precision measurements of electric dipole moments (EDMs) of atoms and molecules have attained the sensitivity to detect indirect signatures of certain particles with masses of more than 10 TeV c^–2. In this Perspective, we discuss recent developments in the measurement and interpretation of EDMs, and assess proposed techniques for future experiments that could push experimental limits on T-violating BSM physics to the PeV scale.

质量为几个TeV c ^–2的新基本粒子可以解释观察到的现象，粒子物理的标准模型（SM）无法解释这些现象，包括暗物质的微观起源以及物质对反物质的宏观失衡。宇宙。但是，尚未在大型强子对撞机（LHC）上检测到TeV尺度的SM以外（BSM）粒子。通过最新的创新，通过低能量精确测量原子和分子的电偶极矩（EDM）来寻找违反时间反转对称性（T）的方法，已经获得了检测质量大于10 TeV c的某些粒子的间接特征的灵敏性。^–2。在此观点中，我们讨论了EDM的测量和解释方面的最新进展，并评估了为将来的实验所提议的技术，这些技术可能将违反TSM的BSM物理学的实验极限推向PeV规模。
