An N=2 SUSY Gauge Model for Dynamical Breaking of the Grand Unified SU(5) Symmetry

Abstract

We construct an extension of the recently proposed dynamical model for the breaking of SU(5)${}_{\mathrm{GUT}}$ gauge symmetry, in which a pair of massless chiral supermultiplets for Higgs doublets are naturally obtained. We point out that a model at a specific point in the parameter space of superpotential is regarded as a low-energy effective theory of an N=2 supersymmetric gauge model for the strongly interacting hypercolor sector.
