Radiative corrections in grand unified theories based onN=1supergravity. II. Gauge theories

Ashoke Sen

Open publisher page 2 citations

Abstract

The effect of radiative corrections in supersymmetric grand unified theories with soft- supersymmetry-breaking terms induced by N=1 supergravity is analyzed. It is shown that any mass hierarchy present in the limit of unbroken supersymmetry is stable under radiative corrections induced by soft-supersymmetry-breaking terms, provided the theory does not contain a light singlet field that transforms as a singlet under the unbroken subgroup of the theory below the grand-unification scale.
