Vacuum stability and string density of states

I shall discuss constraints on the distribution of graded degrees of freedom in classically stable (non-supersymmetric) string vacua. In particular, I shall show that the spectrum of physical excitations not only must enjoy asymptotic supersymmetry but, at very large mass, bosonic and fermionic states must follow a universal oscillating pattern, whose frequencies are related to the zeros of the Riemann zeta-function.
