DILATON STABILIZATION IN THE CONTEXT OF DYNAMICAL SUPERSYMMETRY BREAKING THROUGH GAUGINO CONDENSATION

We study gaugino condensation in the context of superstring effective theories using the linear multiplet formulation for the dilaton superf ield. Including non-perturbative corrections to the Kahler potential f or the dilaton may naturally achieve dilaton stabilization, with super symmetry breaking and gaugino condensation; these three issues are int errelated in a very simple way. In a toy model with a single static co ndensate, a dilaton vev is found within a phenomenologically interesti ng range. The effective theory differs significantly from condensate m odels studied previously in the chiral formulation.
