Description
The viability of a possible cosmological scenario is investigated.
The theoretical framework is the constrained next-to-minimal
supersymmetric standard model (cNMSSM), with a gravitino playing the
role of the lightest
supersymmetric particle (LSP) and a neutralino acting as the
next-to-lightest
supersymmetric particle (NLSP). All the necessary constraints from
colliders and cosmology have been taken into account. For gravitino
we have considered the two usual production mechanisms, namely
out-of equillibrium decay from the NLSP, and scattering processes
from the thermal bath. The maximum allowed reheating temperature
after inflation, as well as the maximum allowed gravitino mass are
determined.
