Abstract:
We consider the Schwarz-Sen spectrum of elementary electrically charged massive NR=1/2N_R=1/2 states of the four-dimensional heterotic string and show them to correspond to extreme black hole solutions with scalar-Maxwell parameter a=3a=\sqrt 3 or 11 according as NL=1N_L=1 or NL>1N_L>1. The solitonic magnetically charged spectrum conjectured by Schwarz and Sen on the basis of string/fivebrane duality is also described by extreme black holes.
