COMMENTS ON HIERARCHICAL SYMMETRY BREAKING IN EFFECTTVE THEORY OF CALABI-YAU COMPACTIFIED SUPERSTRING
Keyword(s):
We re-examine the possibility of large hierarchical symmetry breaking in the effective field theory of Calabi-Yau compactified superstring. We introduce the general superpotential containing the allowed moduli couplings. In certain manifolds one-loop radiative correction gives the non-trivial minimum and that solution suggests the possibility of large hierarchical symmetry breaking. To realize such a large hierarchy, it seems to require that 27(h2,1 + h1,1) > 48π2 and H1 ( End T) chiral superfields should have certain types of couplings to moduli fields.
