From Charge-Conjugation Asymmetries to the Trilinear Gluon Coupling

In quark-quark scattering where a hard gluon is radiated, a charge-conjugation asymmetry is examined and found to be large. The perturbative quantum-chromodynamic prediction for this asymmetry is compared with that for an Abelian theory and an appreciable difference is found. The specific role of the trilinear coupling is significant. A program is set forth for three-jet experiments in hadron-hadron collisions in which the non-Abelian issue can be studied.
