ABSTRACT: Inflation may occur while rolling into the metastable supersymmetry-breaking
vacuum of massive supersymmetric QCD. We explore the range of parameters in which slow-
roll inflation and long-lived metastable supersymmetry breaking may be simultaneously real-
ized. The end of slow-roll inflation in this context coincides with the spontaneous breaking of
a global symmetry, which may give rise to significant curvature perturbations via inhomoge-
nous preheating. Such spontaneous symmetry breaking at the end of inflation may give rise
to observable non-gaussianities, distinguishing this scenario from more conventional models
of supersymmetric hybrid inflation.
