Soft gluon–quark–antiquark emission in QCD hard scattering
Abstract We consider the radiation of a soft gluon (g) and a soft quark–antiquark ( $$q{{\bar{q}}}$$ q q ¯ ) pair in QCD hard scattering. In the soft limit the scattering amplitude has a singular behaviour that is factorized and controlled by a soft current, which has a process-independent structure...
