Abstract
The virtual massive gauge boson effects on several observables in the process of charged fermion pairs production at colliders are computed up to the TeV energy range in the Standard Model, working in the ``-peak subtracted'' representation. It is shown that these effects increase regularly with energy, approaching the typical ten percent relative size. A careful numerical evaluation is proposed, where the conditions dictated by gauge invariance are consistently implemented.
