Abstract

Inflation based on a single chiral superfield (the inflaton) in N = 1 supergravity has been shown to be incompatible with the so-called thermal constraint requiring a high temperature minimum at a point at which the zero-temperature scalar potential is flat, in a theory using fields with minimal scalar kinetic terms. Here we show that by modifying the kinetic terms of the inflaton, one can satisfy the thermal constraint without introducing additional fields or small parameters.
