Query: Phenomenology of the relic dilaton background   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).
