摘要：

We study the effects of the Coulomb singularity for off-shell W-pair production in the relativistic approach, coming out of the continuum. This involves a careful analysis of the interplay between the Coulomb singularity, the decay width of the W bosons, and their off-shellness. We have observed screening effects related to the finite W width and the off-shellness. In the LEP200 energy range these screening effects and the relativistic effects turn out to be non-negligible.
