The radiative decay modes 11 ~ , ,Z have becn Cound to be viable at SSC/LIlC Cordetection oCan intermediate mass range lliggs boson expected in the standard model (SM). A precise measurement of the decay widths of these modes may be used to distinguish among thcories beyond the SM. We present results obtained Corthe respective decay widths in minimal extensions oCthe SM: leCt-right symmetric models with a minimal Higgs potential, the minimal supersymmetric standard model, and SU(2) x U(I) invariant Lagrangians in which any new physics appears as nonrenormalizable, effective interactions. \Ve condude that only in the last ca..<;e the S~I decay widths Corthese radiative modes may be enhanced.
