Abstract
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.
