摘要：

The contributions from two QED processes, e+e− →μ+μ−γγ and e+e− →μ+μ−, to the heavy lepton signal observed in muon inclusive final states in e+e− annihilation are calculated for the experimental setup of PLUTO in the energy range 4–5 GeV. Some modifications in the usual calculation techniques for QED processes are described. We discuss the observability of the sequential heavy lepton signal at PETRA energies and show which experimental cuts sufficiently damp the background to signal ratio. © 1979, Springer-Verlag.
