Abstract

We re-examine the inflationary scenario in the standard SU(5) model with Coleman-Weinberg symmetry breaking and point out difficulties which may be resolved in a broken supersymmetric model. Because of a partial cancellation at the one-loop level, the effective potential in a broken supersymmetric theory may be much flatter than in standard SU(5), thus permitting a greater amount of inflation.
