We examine the effects of anomalous U(1)_A gauge symmetry on softsupersymmetry breaking terms while incorporating the stabilization of themodulus-axion multiplet responsible for the Green-Schwarz (GS) anomalycancellation mechanism. In case of the KKLT stabilization of the GS modulus,soft terms are determined by the GS modulus mediation, the anomaly mediationand the U(1)_A mediation which are generically comparable to each other,thereby yielding the mirage mediation pattern of superparticle masses at lowenergy scale. Independently of the mechanism of moduli stabilization andsupersymmetry breaking, the U(1)_A D-term potential can not be an upliftingpotential for de Sitter vacuum when the gravitino mass is smaller than thePlanck scale by many orders of magnitude. We also discuss some features of thesupersymmetry breaking by red-shifted anti-brane which is a key element of theKKLT moduli stabilization.Comment: 32 pages; references are adde
