  In the scenario recently proposed by Arkani-Hamed and Dimopoulos, the
supersymmetric scalar particles are all very heavy, at least of the order of
$10^9$ GeV but the gauginos, higgsino, and one of the CP-even neutral Higgs
bosons remain light under a TeV. In addition to gluino production, the first
SUSY signature would be pair production of neutralinos and/or charginos. Here
we study, with explicit CP violation, the production of neutralinos and
charginos at hadronic colliders as well as the possible decay modes. We notice
that the branching ratio of the neutralino radiative decay can be sizable
unlike the case with light sfermions. In particular, the decay of N3->N1+gamma
has a branching ratio of the order O(1) percent. In colliders, it would give
rise to signatures of an isolated single photon plus missing energy.
