A detailed analysis of SU(5) supergravity unification

The analysis of SU(5) mode is carried out under the assumptions of mo, mg<1 TeV and MH3<3MG, where mo is the universal scalar mass, mg the gaugino mass, MH3 the Higgs triplet mass and MG the unification mass. The combined experimental constraints from LEP and CDF on the SUSY mass spectrum and the experimental proton lifetime constraint from Kamiokande are imposed. Under the above constraints masses of the 31 supersymmetric particles are determined in terms of the four parameters, and these masses are strongly correlated. Thus the theory predicts that either a neutral Higgs or a light Wino will be observable at LEP2. The No-Scale model is found to be phenomenologically not viable as it violates the proton life-time limits under the assumed theoretical constraints. (R.P.) 12 refs.; 2 figs
