Electroweak 2→2 amplitudes for electron-positron annihilation at TeV energies
Abstract
The nonradiative scattering amplitudes for electron-positron annihilation into quark and lepton pairs in the TeV energy range are calculated in the double-logarithmic approximation. The expressions for the amplitudes are obtained using infrared evolution equations with different cutoffs for virtual photons and for W and Z bosons and compared with previous results obtained with a universal cutoff.
