Description

A model independent analysis of the particle spectrum and the interaction vertices of supergravity GUT models is given. The analysis interpolates between the models which produce SU(2) x U(1) breaking at the tree level and those where SU(2) x U(1) is broken dynamically from renormalization group loop corrections. General relations for wino and zino masses are obtained. The decays of W and Z into photino, wino and zino modes and their branching ratios in various leptonic and hadronic channels are discussed for theories which possess a light photino. (orig.)
