英文摘要: We study the direct mediation of metastable supersymmetry breaking by a Phi(2)-deformation to the ISS model and extend it by splitting both Tr Phi and Tr Phi(2) terms in the superpotential and gauging the flavor symmetry. We find that with such an extension enough-long-lived metastable vacua can be obtained and the proper gaugino masses can be generated. Also, this allows for constructing a kind of models which can avoid the Landau pole problem. Especially, in our metastable vacua there exist a large region for the parameter m(3) which can satisfy the phenomenology requirements and allow for a low SUSY-breaking scale (h mu(2) similar to 100 TeV).
