Description

Infrared singularities in perturbative Quantum Chromodynamics (QCD) are captured by the Soft function, which can be calculated efficiently in terms of multiparton webs. Web is a closed set of diagrams whose colour and kinematics mix through a web mixing matrix. The web mixing matrices are computed using a well known replica trick algorithm. We present a package implemented in Mathematica to calculate these mixing matrices. Along with the package, we provide benchmark points for several state-of-the art computations.
