  A low reheating temperature is now well motivated by the recently
reconsidered gravitino problem, if we incorporate supergravity. In this
article, we propose a model which naturally realizes a low reheating
temperature. The model is based on the next to minimal supersymmetric standard
model (NMSSM) by identifying a singlet scalar field as the inflaton. This
entertains the possibility that the inflaton may be detected at future
colliders, such as the LHC.
