论文摘要
电荷保守和保利排除原理是由粒子物理标准模型中的基本对称性产生的，通常被视为公理。对这些对称性的小违规行为的高精度测试可能指向新的物理学。在这里，我们考虑了三个违反这些过程的模型，这些模型将在\ MJD \实验的高纯晶锗探测器中产生可检测的电离。使用37.5公斤的暴露，我们报告了电子平均寿命的下限，从而提高了$ e \ rightarrow的最佳限制nν_e\ overline {ν_e}ν_e$衰减通道的范围超过了一个数量级。我们还提出了对Pauli排除原则的两种类型的搜索，对在对称量子状态下要发现的电子的可能性设定了限制。
Charge conservation and the Pauli exclusion principle result from fundamental symmetries in the standard model of particle physics, and are typically taken as axiomatic. High-precision tests for small violations of these symmetries could point to new physics. Here we consider three models for violation of these processes, which would produce detectable ionization in the high-purity germanium detectors of the \MJD\ experiment. Using a 37.5 kg-yr exposure, we report a lower limit on the electron mean lifetime, improving the previous best limit for the $e \rightarrow ν_e \overline{ν_e} ν_e$ decay channel by more than an order of magnitude. We also present searches for two types of violation of the Pauli exclusion principle, setting limits on the probability of an electron to be found in a symmetric quantum state.
