Why is the Higgs doublet light?

Abstract

We consider a possible mechanism for the explanation of the doublet-triplet mass hierarchy in the grand unified theories. The Higgs doublet is automatically light since it is related by a certain "custodial" SU(2)_C symmetry to another doublet which after GUT symmetry breaking becomes an unphysical Higgs. Custodial symmetry may or may not be a part of GUT symmetry. An explicit example of SUSY GUT is constructed.
