Abstract

We compute the leading-order back-reaction to dilaton-driven inflation, due to graviton, dilaton and gauge-boson production. The one-loop effect turns out to be non-vanishing (unlike the case for pure de-Sitter and for power-law inflation), to be of relative order ℓ_P²H²(t), and to have the correct sign for favouring the exit to a FRW phase.
