Scientific paper

Superstring models with an intermediate mass scale possess a novel
mechanism for generating the baryon asymmetry in the universe. It
involves the out-of-equilibrium decay of heavy particles at temperatures
close to the electroweak scale. The gravitino problem encountered in
many supergravity models is automatically resolved.
