Abstract

We present a number of qualitative arguments which strongly suggest that extremal dyonic black holes in the 4-dimensional low energy, classical field theory limit of toroidally compactified heterotic string theory represent largely degenerate classes of states in the quantum theory. We propose a simple expression for the full non-perturbative degeneracy, which contains no free continuous parameters and reproduces the Bekenstein-Hawking S = A/4GN in the large-area limit (with the 1/4 arising from microphysics). We sketch the elements of a physical picture leading to this expression: the holes support much hair, such that in counting it we are led to an effective string theory, and a matching condition whose solutions give the degeneracy.
