Supersymmetric mass spectrum in SU(5) supergravity grand unification
Abstract
A detailed analysis of predictions of SU(5) supergravity grand unification within the framework of radiative breaking of SU(2)xU(1) is presented. The masses of the 31 new supersymmetric particles depend on only four parameters. The full parameter space is considered and found to be strongly restricted by proton decay bounds if no extreme fine tuning is required and the Higgs triplet mass is required to be not greater than 3M sub G. However, within these conditions, SU(5) supergravity grand unification is already making predictions that can be experimentally tested by LEP 2, the LHC, and the SSC.
