VIP合作正在INFN（意大利）地下Gran Sasso实验室的极低宇宙背景环境中对电子进行泡利不相容原理的高精度测试。实验技术包括在铜导体中引入直流电流，当K壳层已经被两个电子占据时，寻找由于PEP禁止的原子从铜的L壳层到K壳层的跃迁而产生的X射线发射。VIP对PEP破坏概率12β2<4.7×10−29设定了上限，升级后的VIP-2实验的目的是将这一结果至少提高两个数量级。实验装置和初步数据分析的结果将被提交。
The VIP collaboration is performing high precision tests of the Pauli Exclusion Principle for electrons in the extremely low cosmic background environment of the Underground Gran Sasso Laboratories of INFN (Italy). The experimental technique consists in introducing a DC current in a copper conductor, searching for the X-rays emission due to a PEP-forbidden atomic transition from the L shell to the K shell of copper when the K shell is already occupied by two electrons. VIP set un upper limit on the PEP violation probability 12β2<4.7×10−29 , the aim of the upgraded VIP-2 experiment is to improve this result by two orders of magnitude at least. The experimental setup and the results of preliminary data analyses will be presented.
