Scientific paper

We delineate the domain of supersymmetry breaking parameters in minimal supergravity models for which the cosmological relic photino density is no larger than the closure density. Demanding that the relic density equal the closure density as suggested by inflationary cosmology suggests mq~ ~ 42 GeV + 0.89 mg~. We point out that several supergravity scenarios for the monojet events at the CERN pp Collider would yield a relic density considerably greater than the closure density.
