  Probability distributions for correlation functions of particles interacting
via random-valued fields are discussed as a novel tool for determining the
spectrum of a theory. In particular, this method is used to determine the
energies of universal N-body clusters tied to Efimov trimers, for even N, by
investigating the distribution of a correlation function of two particles at
unitarity. Using numerical evidence that this distribution is log-normal, an
analytical prediction for the N-dependence of the N-body binding energies is
made.
