Detecting and Studying $e^{+}{e}^{-}\to H^0{A}^0,H^{+}{H}^{-}$ in the MSSM: Implications of Supersymmetric Decays and Discriminating GUT Scenarios

Abstract

We demonstrate that supersymmetric decays, as typified by the predictions of several GUT-scale boundary condition choices, do not prevent detection of $Z^{\ast }\to H^0{A}^0,H^{+}{H}^{-}$, at a $1-4$ TeV $e^{+}{e}^{-}$ or ${\mu }^{+}{\mu }^{-}$ collider operating at anticipated luminosity. For much of parameter space the relative branching ratios for various 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.
