Sažetak
The authors consider the symmetry breaking of the SU(5) symmetry to the physical SU(3)*SU(2)*U(1) symmetry induced by an effective 75-dimensional Higgs field. They present a one-loop renormalization-group analysis of the stability of the SU(3)*SU(2)*U(1) symmetry of the absolute minimum. They have found regions in the full parameter space where all stability requirements, between the Planck scale 10/sup 19/ GeV and the typical GUT scale 10/sup 16/ GeV, are satisfied. The usefulness of the sum-of-square potential in the stability analysis is explicitly demonstrated. (7 References).
