The nearest-neighbor mass-spacing distribution of the meson and baryon spectrum (up to 2.5 GeV) is described by the Wigner surmise corresponding to the statistics of the Gaussian orthogonal ensemble of random matrix theory. This can be viewed as a manifestation of quantum chaos in hadrons.

14.20.-c - Baryons (including antiparticles).
14.40.-n - Mesons.
05.45.Mt - Semiclassical chaos ("quantum chaos") .
