Comments on the production and decay of charged heavy leptons

Several issues concerning charged heavy leptons ($L^{\pm }$) are considered for the production and decay sequence $e^{+}+e^{-}\to L^{+}+L^{-}\to \mathrm{decay}$ products. We note that certain angular distributions of decay products contain information on the $L^{+}{L}^{-}$ production process independent of any details of the decays. For leptonic decays $L\to {\nu }_L+l+{\overline{\nu }}_l$ ($l=e or \mu$) other aspects of the joint energy and angular distributions provide further information concerning the helicity structure of the weak leptonic interactions. Several other issues concerning semileptonic decays are also discussed. In particular some special cases are described where parity-violating effects would uniquely signal the presence of second-class currents.
