Abstract：
Thermalization of quark matter and antiquark matter can be influenced by the scattering processes from quark-quark-antiquark to quark-quark-antiquark in quark-gluon matter, and the scattering amplitudes of such processes are the basis of studying thermalization. According to the perturbative QCD, a Fortran code for deriving individual squared amplitudes of all the qqq→qqq scattering Feynman diagrams and interference terms between different diagrams at order α⁴_s is written and corresponding squared amplitudes and interference terms are derived.
