Abstract

We consider the Schwarz-Sen spectrum of elementary electrically charged massive states of the four-dimensional heterotic string and show the maximum spin supermultiplets to correspond to extreme black hole solutions. The states and states (with vanishing left-moving internal momentum) admit a single scalar-Maxwell description with parameters or , respectively. The corresponding solitonic magnetically charged spectrum conjectured by Schwarz and Sen on the basis of -duality is also described by extreme black holes.
