In QCD, the soft function exponentiate in terms of diagrams known as webs.We have defined Cwebs or correlator webs which are useful in the calculation of soft function exponentiation at higher perturbative orders.We review the results of the four-loop Cweb mixing matrices.We also provide a direct construction of a few of the mixing matrices without applying the complicated steps of the replica trick. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
