Abstract
In a supersymmetry scenario with a mass hierarchy ${\mathrm{m}}_{\mathrm{g}\mathrm{\ifmmode \tilde{}\else \~{}\fi{}}}$\ensuremath{\approxeq}${\mathrm{m}}_{\mathrm{q}\mathrm{\ifmmode \tilde{}\else \~{}\fi{}}}$>${\mathrm{m}}_{\mathrm{\ensuremath{\omega}}\mathrm{\ifmmode \tilde{}\else \~{}\fi{}}}$>${\mathrm{m}}_{\mathrm{l}\mathrm{\ifmmode \tilde{}\else \~{}\fi{}}}$ , gluino-scalar quark pair production followed by the decay chain g\ifmmode \tilde{}\else \~{}\fi{}\ensuremath{\rightarrow}q\ifmmode \tilde{}\else \~{}\fi{} q\ifmmode\bar\else\textasciimacron\fi{}(q\ifmmode \tilde{}\else \~{}\fi{}\ifmmode\bar\else\textasciimacron\fi{}q), q\ifmmode \tilde{}\else \~{}\fi{}\ensuremath{\rightarrow}\ensuremath{\omega}\ifmmode \tilde{}\else \~{}\fi{}q, \ensuremath{\omega}\ifmmode \tilde{}\else \~{}\fi{}\ensuremath{\rightarrow}\ensuremath{\mu}\ifmmode \tilde{}\else \~{}\fi{}\ensuremath{\nu}(\ensuremath{\mu}\ensuremath{\nu}\ifmmode \tilde{}\else \~{}\fi{}), \ensuremath{\mu}\ifmmode \tilde{}\else \~{}\fi{}\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\gamma}\ifmmode \tilde{}\else \~{}\fi{} leads to like-sign and unlike-sign dimuons with comparable rates and possibly little accompanying hadronic activity; such events will often contain strange particles. Predictions are made for the dimuon distributions. The possible relevance to dimuon observations by Arnison et al. is addressed.
