Two-loop high-energy electroweak logarithmic corrections in a spontaneously brokenSU(2)gauge model

Abstract

We present the complete analytical result for the two-loop logarithmically enhanced contributions to the high-energy asymptotic behavior of the vector form factor and 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 to the neutral current four-fermion processes at high energies.
