✦ Synopsis

We present a general differential cross section for the process eT + r-+ y + U 7-Us -p , Y~,I + 5, + e+ + Fu T yp Our results hold for V, A, S, P, T couplings and do not depend on the pe universality assumption. Dependences on arbitrary beam polarizations, final state electron, and muon longitudinal polarizations, and final state electron and muon masses have been included. An analytic expression for du/dE,dE,d cos 8u has been obtained. We show that it is possible to investigate the leptonic decay of U to the same level as that for the muon decay.
