Abstract
We study dynamical moduli stabilization driven by gaugino condensation in supergravity. In the presenceof background radiation, there exists a region of initial conditions leading to successful stabilization.We point out that most of the allowed region corresponds to initial Hubble rate H close to the scale ofcondensation Λ, which is the natural cutoff of the effective theory. We first show thatincluding the condensate dynamics sets a strong bound on the initial conditions. We then find that(complete) decoupling of the condensate happens at H about two orders of magnitude below Λ.This bound implies that in the usual scenario with the condensate integrated out, only the vicinity ofthe minimum leads to stabilization. Finally, we discuss the effects of thermal corrections.
