Abstract
We solve the coupled Boltzmann equation for the system of light photinos interacting with pions and [Formula presented]’s (the gluon-gluino bound state) to determine the relic abundance of light photinos in the light gaugino scenario. Cosmology bounds the ratio [Formula presented] of the [Formula presented] mass to the [Formula presented] mass to be less than about [Formula presented]. We also use a model Lagrangian embodying crossing symmetry between the [Formula presented] and [Formula presented] reactions to identify cosmologically favored regions of [Formula presented] lifetime as a function of [Formula presented] and [Formula presented] masses.
