摘要
We construct a supersymmetric grand unified model in which a dynamical symmetry breaking of SU(5)(GUT) generates large masses for color-triplet Higgs multiplets while keeping SU(2)(L)-doublet Higgs multiplets naturally light. The vanishing masses for the Higgs doublets are guaranteed by the Peccei-Quinn symmetry. We also show that the Peccei-Quinn symmetry suppresses the dangerous dimension 5 operators for the nucleon decay.
