Phenomenology of the relic dilaton background

Abstract

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 contracted version of a talk given at the 15th SIGRAV Conference on "General Relativity and Gravitational Physics" (Villa Mondragone, Roma, September 2002).
