Title:
Chaos in the hadron spectrum
Abstract:
I will show that the low-energy hadron spectrum exhibits some universal
statistical properties. In particular, the nearest-neighbor mass-spacing
distribution is described by the Wigner surmise corresponding to the statistics
of the Gaussian orthogonal ensemble of random matrix theory. These properties
of the spectrum are common to quantum systems with essentially chaotic dynamics.
It is interesting to see how or whether such statistical properties emerge
from quark models and lattice QCD calculations.
