We present a supersymmetry-breaking scenario in which both the breaking inthe hidden sector with no-scale type supergravity and that in the observablesector with gauge mediation are taken into account. The breaking scales in thehidden and observable sectors are related through the vanishing condition ofthe cosmological constant with a brane-world picture in mind. Suppressingflavor-changing neutral currents, we can naturally obtain the gravitino,Higgs(ino), and soft masses of the electroweak scale.Comment: 7 pages, Late
