QCD CORRECTIONS TO VECTOR BOSON SELF-ENERGIES IN THE STANDARD MODEL

The O (αs) corrections to the vacuum polarization tensor of the gauge bosons are presented for both light and heavy quark flavours in the standard model of electroweak interactions on the basis of a running coupling constant αs. The influence of Υ{hooked}, Tb and θ resonance as well as the proper threshold behaviour of the imaginary part of the vacuum polarization function are incorporated in the analysis. The real part is calculated numerically through the properly subtracted dispersion relation. A set of FORTRAN routines that implements the scheme is described. © 1990.
