We study the 4-jet and photon plus 3-jet decays of orthoquarkonia, 3S1(QQ)→GGGG+GGqq→4 jets, 3S1(QQ→γGGG+γGqq→γ+3 jets. We show that the characteristic features of the jet distributions in the final state are determined by the 3-gluon vertex of quantum chromodynamics. These decays of a heavy quarkonium resonance (toponium) will offer clear signals for the gluons' self-coupling which can establish QCD as a local non-abelian gauge theory.
