Despite the challenging nature of the signals in these models the long-lived gluino can be discovered with masses above 2 TeV at the LHC. At a future linear collider we will be able to observe the renormalization group effects from split supersymmetry on the chargino/neutralino mixing parameters, using measurements of the neutralino and chargino masses and cross sections. This indirect determination of chargino/neutralino anomalous Yukawa couplings is an important check for supersymmetric models in general.6pp. To appear in the proceedings of International Conference on Linear Colliders (LCWS 05), Stanford, USA, 18-22 Mar 2005High Energy Physics - Phenomenologytext
