Description
In this work we present the tools developed for the automatization of the calculation of the soft anomalous dimension matrices for the heavy-quark hadroproduction processes at one- and two-loop accuracy in QCD. The foundation of this procedure is the construction of orthogonal color basis for $2 \rightarrow n$ processes which will also be discussed. The application of these tools is demonstrated on the examples of $t\bar t j$ and $t\bar t t \bar t$ hadroproductions, making a step forward towards implementing a procedure for the resummation of soft-gluon emission logarithms for these processes.
