Electroweak 2 -> 2 amplitudes for electron-positron annihilation at TeV energies
arXiv:hep-ph/0309230 · doi:10.1103/PhysRevD.69.034012
Abstract
The non-radiative 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 cut-offs for virtual photons and for W and Z bosons, and compared with previous results obtained with an universal cut-off.
