O(alpha) electroweak corrections to the processes e+e- -> tau-tau+, c bar-c, b bar-b, t bar-t: a comparison

Abstract

We present the electroweak one-loop corrections to the processes e+e- -> f bar-f, f = tau, c, b, t, at energies relevant for a future linear collider. The results of two independent calculations are compared and agreement is found at a technical-precision level of ten to twelve digits.
