Acoplanar Di-leptons and Mixed events on the basis of two supergravity model predictions

We propose a search for typical signatures produced by charginos, neutralinos and sleptons on the basis of two supergravity model predictions, at the highest e(+)e(-) energy which will be available with LEP-II. The typical signatures are of two main classes: i) <<pure leptonic>> states; ii) <<mixed lepton-jets>> states. The <<pure leptonic>> states consist of acoplanar di-leptons with <<leading>> and <<non-leading>> leptonic components plus multi-di-lepton states. The <<mixed lepton-jets>> states contain at least two jets and one or three leptons plus missing momenta. All these final states represent clear signatures for SUSY. These models are at present the most reliable in terms of physically sound assumptions.
