Double-logarithmic (Sudakov) asymptotics at the theory of electroweak interactions

B. I. Ermolaev, M. Greco, S. M. Oliveira +1

Accounting for double-logarithmic contributions to high-energy (>> 100 GeV) e^+ e^- annihilation into a quark or a lepton pair in the kinematics where the final particles are colin…
