Description
Considering gravitino dark matter scenarios, we study constraints on the reheating
temperature of inflation. Within the framework of the constrained minimal
supersymmetric Standard Model (CMSSM), we find a maximum reheating temperature of
about 10^7 GeV taking into account bound-state effects on the primordial 6Li
abundance. We show that late-time entropy production can relax this constraint
significantly. With a substantial entropy release after the decoupling of the
lightest Standard Model superpartner, thermal leptogenesis remains a viable
explanation of the cosmic baryon asymmetry within the CMSSM.
