# Chaotic behavior in field and string theory

My talk will be divided into two parts: In the first I will present a novel

measure of chaotic scattering amplitudes. For chaotic scattering the distribution function is given

by the β-ensemble of random matrix theory (RMT). We show that amplitudes of one highly

excited string (HES) state with two or three scalars in open bosonic string theory admit

this behavior. Quite remarkably this measure applies also to the distributin of non-trivial

zeros of the Riemann zeta function.
