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 λ1 g <λ2 should be satisfied, where λ1,2 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.
