Conference paper
Part of the Acta Physica Austriaca book series (FEWBODY, volume 26/1984)

Abstract

The purpose of this talk is to discuss some results obtained from the Monte Carlo (M.C.) simulation of the combined production and decay process e+e→τ+τ (γ), τ→υ e(μ, π, ρ …) based on the O(α3) QED calculations, including Z0 exchange (in the low energy approximation). The effects due to finite mass of τ, and to spin polarization of e± and τ± are also included. In this way all possible effects which would produce systematic variation of the cross section, down to 1 % level, are under control. Thus, accuracy level is assured from the τ production threshold up to the highest PETRA/PEP energies (\(\sqrt s\) ~ 45 GeV).
