摘要：We study the quark-antiquark-gluon techniques in SU(3) lattice QCD, for different geometries,
namely angles of 0, 45, 60, 90, 120, 135 and 180 degrees, between the quark-gluon and the
antiquark-gluon segments. We calculate the form of the static potential and discuss whether, or
not, two-body inter- actions exist between the three different bodies. We also study the existence
of repulsion between the strings. We also mention the interactions between three gluon systems.
