A method for taking into account hard-photon emission in four-fermion processes proceeding in the s channel is described. The application of this method is exemplified by numerically estimating one-loop electroweak corrections to observables (cross sections and asymmetries) of the reaction e{sup −}e{sup +} → μ{sup −}μ{sup +}(γ) involving longitudinally polarized electrons and proceeding at energies below the Z-resonance energy.
