Inflation and Inverse Symmetry Breaking

Abstract

An inflation model with inverse symmetry breaking of two scalar fields is proposed. Constraints on the parameters for a successful inflation are obtained. In general the inequality ${\lambda }_1\ll g<{\lambda }_2$ should be satisfied, where ${\lambda }_{1,2}$ and $g$ are the coupling constants for self interaction and mutual interaction of two scalar fields respectively. An example with $SU(5)$ GUTs phase transition and numerical study are presented. This model introduce a new mechanism for the onset of inflation.
