标题： Spectral-statistics properties of the experimental and theoretical light meson spectra

摘要： 我们对轻子谱展示出的光谱涨落进行了稳健分析。 这一分析提供了有关轻子中混沌程度的信息，并可能有助于深入了解潜在的相互作用。 我们的分析揭示，轻子谱的统计特性接近但不完全等于混沌系统的特性。 此外，我们分析了多个理论谱，包括最新的格点QCD计算。 除一个例外，它们的统计特性接近于一般的可积系统，因此与实验谱不兼容。 显示英文摘要

摘要： We present a robust analysis of the spectral fluctuations exhibited by the light meson spectrum. This analysis provides information about the degree of chaos in light mesons and may be useful to get some insight on the underlying interactions. Our analysis unveils that the statistical properties of the light meson spectrum are close, but not exactly equal, to those of chaotic systems. In addition, we have analyzed several theoretical spectra including the latest lattice QCD calculation. With a single exception, their statistical properties are close to those of a generic integrable system, and thus incompatible with the experimental spectrum.
