Phenomenology of the relic dilaton background
M. Gasperini
We discuss the expected amplitude of a cosmic background of massive, non-relativistic dilatons, and we report recent results about its possible detection. This paper is a contracte…
Scalar fluctuations in dilatonic brane-worlds
V. Bozza, M. Gasperini, G. Veneziano
We derive and solve the full set of scalar perturbation equations for a class of five-dimensional brane--world solutions, with a dilaton scalar field coupled to the bulk cosmologic…
Production and detection of relic dilatons in string cosmology
M. Gasperini
This paper summarizes the contribution presented at the {\sl IX Marcel Grossmann Meeting} (Rome, July 2000). It is stressed, in particular, that a non-relativistic background of ul…
Weighing the string mass with the COBE data
M. Gasperini
In the context of the pre-big bang scenario the large-scale CMB anisotropy can be seeded by a primordial background of very light (or massless) axion fluctuations. In that case the…
Testing string cosmology with gravity wave detectors
M. Gasperini
The general properties of the gravity wave backgrounds of cosmological origin are reviewed and briefly discussed, with emphasis on the relic background expected from an early pre-b…
Birth of the Universe in string cosmology
M. Gasperini
The decay of the string perturbative vacuum into our present cosmological state is associated to the transition from a phase of growing curvature and growing dilaton, to a phase of…
