Phys. Rev. D 55, 4839–4847 (1997)Gaugino condensation with S duality and field-theoretical threshold correctionsReceived 11 November 1996; published in the issue dated 15 April 1997 We study gaugino condensation in the presence of an intermediate mass scale in the hidden sector. S duality is imposed as an approximate symmetry of the effective supergravity theory. Furthermore, we include in the Kähler potential the renormalization of the gauge coupling and the one-loop threshold corrections at the intermediate scale. It is shown that confinement is indeed achieved. Furthermore, a new running behavior of the dilaton arises which we attribute to S duality. We also discuss the effects of the intermediate scale, and possible phenomenological implications of this model. © 1997 The American Physical Society URL:
