Description
The Soft function that captures the IR singularity of scattering amplitudes exponentiates and the soft anomalous dimension $\Gamma_s$ sits in the exponent. $\Gamma_s$ can be expressed in
terms of sets of Feynman diagrams known as Cwebs. The color of Diagrams in a Cweb mix through Cweb mixing matrices.
In this talk I present a novel approach for the calculation of these matrices which makes the structures present in them transparent and also enables us to make predictions to all orders in perturbation theory for several classes of CWebs.
