Two-loop electroweak corrections for four-fermion processes at LHC and ILC

We present the complete analytical result for the two-loop logarithmically enhanced contributions to the high energy asymptotic behavior of the four-fermion cross section in a spontaneously broken SU(2) gauge model. On the basis of this result we derive the dominant two-loop electroweak corrections for the neutral current four-fermion processes at LHC and ILC, such as Drell-Yan dilepton production and Bhabha scattering.
