Radiative corrections to muon pair and quark pair production in electron-positron collisions in the Z0 region

A calculation of first-order radiative corrections to the process e⁺e^?→μ⁺μ^? is presented, which is in particular applicable to the Z₀ region. The emphasis is on a detailed treatment of hard photon effects, which affect the size of the corrections in the Z₀ region considerably. The technique used is that of a Monte Carlo simulation of μ⁺μ^? and μ⁺μ^?γ events. In an appendix the generalization to quark pair production is presented.
