$V(r)=-\alpha_s\sum_{n=0}^\infty A_n \frac{e^{-m_n r}}{r}$
being $m_n$ the glueball spectrum. This potential has an infinite number of contributions. Baryons are expected to be chaotic already with a Coulombian approximation being three-body bound states. But a potential like that above could produce classical chaotic dynamics having an infinite number of terms and producing in this way an infinite numbers of resonances in the KAM series. But to obtain this potential we started with perfectly regular solutions in the quantum field theory!
