We study a generalization of anomaly-mediated supersymmetry breaking (AMSB) scenarios, under the assumption that the effects of the high-scale theory do not completely decouple and D-term type contributions can be therefore present. We investigate the effect of such possible D-term additional contributions to soft scalar masses by requiring that, for non-vanishing, renormalizable Yukawa couplings Y ijk , the sum of squared soft supersymmetry breaking mass parameters, M 2 ijk ≡ m 2 +m 2 +m 2… Expand

The gauge hierarchy achieved by a fine-tuning in the superpotential would be violated in general due to the nonuniversal SUSY-breaking terms, but it is preserved for a certain class of the soft terms derived from a [ital hidden] ansatz. Expand
