Abstract
The full parameter space of supergravity grand unified theory with SU(5)-type p→ν̅ K proton decay is analyzed using renormalization-group-induced electroweak symmetry breaking under the restrictions that the universal scalar mass m₀ and gluino mass are ≤1 TeV (no extreme fine tuning) and the Higgs triplet mass obeys MH₃/MG33 yr allowing a number of predictions concerning the SUSY mass spectrum. Thus either the p→ν̅ K decay mode will be seen at these experiments or a chargino of mass mW̃Further, if (p→ν̅ K)>1.5×1033 yr, then either the light Higgs boson has mass mh≤95 GeV or mW̃≤100 GeV, i.e., either the light Higgs boson or the light chargino (or both) would be observable at LEP2. Thus, the combination of future accelerator and future underground experiments allow for strong experimental tests of this theory.
