Three-loop helicity amplitudes of four-lepton scattering in QED
Giulio Crisanti, Thomas Dave, Pierpaolo Mastrolia +3
We present the analytic expressions of the three-loop virtual corrections to the helicity amplitudes of 2 -> 2 four-fermion scattering processes in massless QED. The contributing F…

High-energy evolution in planar QCD to three loops: the non-conformal contribution
Giacomo Brunello, Simon Caron-Huot, Giulio Crisanti +2
The Balitsky-Kovchegov (BK) equation offers a tractable description of the high-energy growth of gauge-theory scattering amplitudes and the nonlinear saturation effects that eventu…
