Abstract

A characteristic spectrum of relic gravitational radiation is produced by a period of “stringy inflation” in the early Universe. This spectrum is unusual, because the energy density rises rapidly with frequency. We show that correlation experiments with the two gravitational-wave detectors being built for the Laser Interferometric Gravitational Wave Observatory could detect this relic radiation for certain ranges of the parameters that characterize the underlying string cosmology model.
