摘要:

泡利不相容原理(PEP)代表了现代物理学的基本原理之一,即使没有令人信服的理由怀疑它的有效性,它仍然引发了一场激烈的辩论,因为仍然缺少直观的基本解释,而且因为它在物理学的基本对称性中具有独特的地位。VIP(VIolation of the泡利不相容原理)合作组利用寻找铜中PEP禁戒跃迁的方法,建立了一个新的PEP被电子破坏的概率极限。初始值${1/2}β^{2} \textless 4.5\times 10^{-28}$表示比之前的极限提高了大约两个数量级。VIP的目标是在$10^{-30}$级别推动这一限制。

英文摘要:

The Pauli exclusion principle (PEP) represents one of the basic principles of modern physics and, even if there are no compelling reasons to doubt its validity, it still spurs a lively debate, because an intuitive, elementary explanation is still missing, and because of its unique stand among the basic symmetries of physics. A new limit on the probability that PEP is violated by electrons was estabilished by the VIP (VIolation of the Pauli exclusion principle) Collaboration, using the method of searching for PEP forbidden atomic transitions in copper. The preliminary value, ${1/2}β^{2} \textless 4.5\times 10^{-28}$, represents an improvement of about two orders of magnitude of the previous limit. The goal of VIP is to push this limit at the level of $10^{-30}$.
