摘要：

We present the results of a complete analysis of the one-loop electroweak corrections to e(-)e(+)-->gammagamma, Zgamma, ZZ in the standard model (SM) and the minimal supersymmetric standard model (MSSM). A special emphasis is put on the high energy behavior of the various helicity amplitudes and the way the logarithmic structure is generated. The large magnitude of these effects, which induce striking differences between the SM and MSSM cases at high energies, offers the possibility of making global tests which could check the consistency of these models, and even decide whether any additional new physics is required.
