Lepton distributions from the decay of W̃ pairs at e+e- colliders

We have computed, in detail, the energy and angular distribution of the leptons (l) produced by the decay of W gauginos (W̃) via the reaction e+e-→W̃ ++W̃ l+-νγ̃+l- ν¯ γ̃ within the framework of a supergravity electroweak model. We have also computed the backgrounds to this reaction from the production and subsequent decays of τ+τ- pairs or pairs of new sequential heavy leptons. We conclude that it is possible to distinguish the W̃ from an …
