Abstract

(1978). doi:10.1007/BF02734201, We present numerical estimates for the radiative corrections to the decays L∓ → e∓νeνL, μ∓ νμνL in the context of aV ±A interaction. The radiative corrections change the Michel parameter appreciably from its bareV ±A value, for the decay L∓ → e∓νeνL, and have a measurable effect on the electron energy spectrum.

Abstract

(1978). doi:10.1016/0370-2693(78)90181-8, Annihilation of e + e − into final states with a single electron has been studied with the PLUTO detector at the DORIS storage ring at CMS energies from 3.6 to 5 GeV. In the sample of 4-prong events without any detected photon we observe 21 events which we assign to the reaction e + e − → τ + τ − → νν e + νϱ 0 π . We obtain a branching ratio for τ + → νϱ 0 π + of 0.050 ± 0.015 with an overall systematic uncertainty of 30%. The data are consistent with the ϱπ coming from an A 1 meson.

Abstract

(1976). doi:10.1103/PhysRevD.14.3052, The lepton-number assignment of the charged heavy leptons (suggested by the SLAC-LBL μ±e∓ events) has definite signatures which can be tested experimentally. We study the signatures and calculate the decay rates when the neutral currents are also contributing.
