Dark Matter in Models of String Cosmology
arXiv:hep-ph/9903278 · doi:10.1063/1.59418
Abstract
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.
