Dark Matter in Models of String Cosmology
The origin of dark matter in the universe may be weakly interacting scalar
particles produced by amplification of quantum fluctuations during a period of
dilaton-driven inflation. We present two interesting cases, the case of small
fluctuations, and the resulting nonthermal spectrum, and the case of large
fluctuations of a field with a periodic potential, the QCD axion.Comment: 13 pages LaTeX, uses aipproc.sty, talk presented by R. Brustein at
