Electroweak radiative corrections to b-quark production

The electroweak radiative corrections to the Z0banti b and γbanti b vertices are calculated in 't Hooft-Feynman gauge in the standard model and are given in a compact form in terms of three universal functions. The results are obtained as the equal-mass limit of analogous flavour changing neutral current diagrams which avoids the need for fermion mass renormalization. The box diagram containing an internal top quark that occurs in the process e+e-→banti b is also calculated. (orig.)
