Abstract: We analyze a supersymmetry SUSY breaking model proposed by Intriligator,Seiberg and Shih in a supergravity SUGRA framework. This is a simple andnatural setup which demands neither extra superpotential interactions nor anadditional gauge symmetry. In the SUGRA setup, the U1R symmetry is explicitlybroken by the constant term in the superpotential, and pseudo-moduli fieldnaturally takes non-zero vacuum expectation value through a vanishingcosmological constant condition. Sfermions tend to be heavier than gauginos,and the strong-coupling scale is determined once a ratio of sfermion to gauginomasses is fixed.
