The Soft Anomalous Dimension at four loops in the Regge Limit

The Soft Anomalous Dimension at four loops in the Regge Limit

The soft anomalous dimension governs the infrared divergences of scattering amplitudes in general kinematics to all orders in perturbation theory. By comparing the recent Regge-limit results for $2\to2$ scattering (through Next-to-Next-to-Leading Logarithms) in full colour to a general form for t...
