Description

In perturbative QCD, for the inclusive cross section for the scattering of two coloured particles, we identify graphs which contribute to the general leading order αsub(s)(αsub(s)lnlambda)sup(n) of uncancelled IR divergences, and we sum these contributions (lambda is the IR cut-off). The work is done in the Coulomb gauge; an appendix discusses the Feynman gauge. (orig.)
