There is a class of supersymmetric models which is well-motivated by hints of evidence for SUSY and consistent with all existing data. It is important to study the predictions of these models. They are characterized by M̃N3 ≳ M̃C1 > M̃v > M̃N1 (where Ñi and C̃i are neutralino and chargino mass eigenstates), |μ| ≲ M1 ≲ M2 ≈ MZ, μ < 0, and tan β near 1. Their LEP signatures are mostly unusual. Most produced superpartners are invisible! A good signature is two photons plus large missing energy. There are also excess events at large recoil mass in the single photon plus nothing channel. We list the main signatures for charginos, stops, etc., which are also likely to be unconventional. This class of models will be definitively tested at LEP194 with 100 pb-1 per detector, and almost definitively tested at LEP184.
