Complete O(α) corrections to the process e⁺ e⁻ → b b — •Alejandro Lorca and Tord Riemann — DESY Zeuthen, Platanenallee 6, Zeuthen D-15378 Germany

We present the complete electroweak one-loop corrections to the process e⁺ e⁻ → b b at Tesla energies for a linear e⁺ e⁻ collider. Differential and integrated cross sections are presented as well as asymmetries, where these results are parametrized via form factors. Hard bremsstrahlung and soft photons are also included. The b-mass dependence is studied.
