Abstract
We investigate gravitino dark matter scenarios in which the primordial 6Li production is catalyzed by bound-state formation of long-lived negatively charged particles Xâ with 4He. In the constrained minimal supersymmetric Standard Model (CMSSM) with the stau ÏË1â as the Xâ, the observationally inferred bound on the primordial 6Li abundance allows us to derive a rigid lower limit on the gaugino mass parameter for a standard cosmological history. This limit can have severe implications for supersymmetry searches at the Large Hadron Collider and for the reheating temperature after inflation.
