Abstract

Investigations of possible violations of the Pauli exclusion principle represent critical tests of the microscopic space-time structure and properties. Space-time noncommutativity provides a class of universality for several quantum gravity models. In this context the VIP-2 lead experiment sets the strongest bounds, searching for the Pauli exclusion principle violating atomic transitions in lead, excluding the θ-Poincaré noncommutative quantum gravity models far above the Planck scale for nonvanishing θ_{μν} electriclike components, and up to 6.9×10^{-2} Planck scales if θ_{0i}=0.

摘要

对泡利不相容原理可能违反情况的研究是微观时空结构和性质的关键测试。时空非对易性为几种量子引力模型提供了一类通用性。在此背景下，VIP - 2铅实验设定了最强的界限，搜索铅中违反泡利不相容原理的原子跃迁，排除了对于非零类电分量θμν远高于普朗克尺度以及若θ0i = 0时高达6.9×10−2普朗克尺度的θ - 庞加莱非对易量子引力模型。
