Maximum allowed reheating temperature after inflation
Maximum allowed gravitino mass
Viable parameter space for gravitino dark matter
Abstract
The gravitino dark matter with neutralino NLSP hypothesis is investigated in the framework of NMSSM. We have considered both the thermal and non-thermal gravitino production mechanisms, and we have taken into account all the collider and cosmological constraints. The maximum allowed reheating temperature after inflation, as well as the maximum allowed gravitino mass are determined.
