Abstract

We demonstrate that supersymmetric decays, as typified by the predictions of several grand unified theory (GUT)-scale boundary condition choices, do not prevent detection of $Z^{⋆} \to H^{0} A^{0} {, H}^{+} H^{-}$ , at a $1 - 4 TeV$ $e^{+} e^{-}$ or $μ^{+} μ^{-}$ collider operating at anticipated luminosity. For much of the parameter space the relative branching ratios for various supersymmetric (SUSY) and non-SUSY decays can be measured with sufficient accuracy that different GUT-scale boundary condition choices can be distinguished from one another at a very high confidence level.
