Scientific paper

A class of "realistic" supergravity grand-unified-theory models possessing two W-inos and two Z-inos which lie above and below W+/- and Z0 mass, respectively, are examined. A lower bound on the W-ino mass of ~= 30 GeV is obtained with an upper bound of ~= 250 GeV on the Higgs mass. It is shown that the Z0 decays prominantly into two W-inos if the mass of the W-ino<=MW2. The superpartners of quarks and leptons are shown to be approximately degenerate and in some models have mass <~ 100 GeV.
