Production and decay of heavy leptons in transversely polarized electron-positron annihilation

Abstract

To study the "anomalous" lepton production in the SPEAR $e^{+}{e}^{-}$ annihilation experiment, a detailed theoretical study is undertaken of the leptonic decay distributions for the hypothetical heavy leptons produced in $e^{+}{e}^{-}$ annihilation. Transverse polarizations of the incident electrons and positrons are taken into account in the present calculation. For the leptonic decay of the heavy lepton, both left-handed and right-handed weak currents are considered for the heavy leptons. Numerical results on the momentum and various angular distributions are given. In the numerical computations we take into account the experimental acceptance criteria.
