Phenomenology of Superstrings
We consider the low energy phenomenology of superstrings. In particular we
analyse supersymmetry breaking via gaugino condensate and we compare the
phenomenology of the two different approaches to stabilize the dilaton field.
We study the cosmological constant problem and we show that it is possible to
have supersymmetry broken and zero cosmological constant. Finally, we discuss
the possibility of having an inflationary potential. Requiring that the
potential does not destabilize the dilaton field imposes an upper limit to the
density fluctuations which can be consistent with the COBE data.Comment: 9 pages, no figures, Invited talk given at the general meeting of the
