Abstract

We consider charge-conjugation asymmetries arising from two-gluon exchange and gluon-bremsstrahlung corrections in color-averaged quark-antiquark and quark-quark scattering. At large momentum transfers, such considerations lead to sizable predictions for forward-backward and particle-antiparticle asymmetries in hadron collisions. Jet-antijet differences are discussed and the cleanest tests involve the heavier quarks. The absence of mass singularities and the relationship to two-photon asymmetries are emphasized.
