摘要

Studying e(-)e(+) -%26gt; W-W+ at the one-loop electroweak order, we derive very accurate and simple expressions for the four helicity conserving amplitudes which dominate this process at high energies. The calculations are done in both the standard model and minimal supersymmetric standard model frameworks. Such expressions, called supersimple, nicely emphasize the dynamical contents of each framework. Numerical illustrations are presented, which show the accuracy of this description, and how it can be used for identifying possible additional new physics contributions, like, e. g., anomalous gauge couplings or a new Z%26apos; vector boson exchange. The procedure is useful even if only the standard model is visible at the future linear collider energies.
