Is M$_{t}$ $\sim$ M$_{W}$ ruled out?

A four generation supersymmetric model is proposed, in which the Tevatron ``top-quark'' events are reinterpreted as the production of t^\prime which decays dominantly to bW^+. In this model, m_t\simeq m_W, and t\rta\widetilde t\widetilde\chi^0_1, with \widetilde t\rta c\widetilde\chi^0_1. This decay chain, which rarely produces a hard isolated lepton, would have been missed in all previous top quark searches. A narrow region of the model parameter space exists which cannot yet be ruled out by present data. This model predicts a rich spectrum of new physics which can be probed at LEP-II and the Tevatron.
