Query: Electroweak Corrections to e+e- --> 4 fermions   The calculation of the full electroweak O(alpha) corrections to the
charged-current four-fermion production processes e+e- --> nu_tau tau+ mu-
anti-nu_mu, u anti-d mu- anti-nu_mu, and u anti-d s anti-c is briefly reviewed.
The calculation is performed using the complex-mass scheme for the gauge-boson
resonances. The evaluation of the occurring one-loop tensor integrals, which
include 5- and 6-point functions, requires new techniques. The effects of the
complete O(alpha) corrections to the total cross section and to the
production-angle distribution are discussed and compared to predictions based
on the double-pole approximation, revealing that the latter approximation is
not sufficient to fully exploit the potential of a future linear collider in an
analysis of W-boson pairs at high energies.
