在一定条件下，在N = 1超引力理论的局部超对称破缺扇区中会发生强相互作用。在最小模型中，当标量和赝标量质量ms和mp超过临界值时，就会发生这种情况：（ms 2 + mp2）c= 144πm3 22。预计强相互作用效应将出现在能量量级为λ sc=（6 π 2πm 3 2 MP 1）1 2处。对于非常大的mS，有吸引力的自旋0和自旋2 gravitino-gravitino通道。
A strong interaction is shown to occur, under certain conditions, in the local supersymmetry breaking sector of N = 1 supergravity theories. In the minimal model this happens when the scalar and the pseudosclar masses msand mpare such as to exceed the critical value: (ms2+ mp2)c= 144πm3 22. Strong interaction effects are expected to show up at an energy of order √sc= (6√2πm 3 2 MP 1)1 2. For very large mS, attractive spin-0 and spin-2 gravitino-gravitino channels are found.
