| Abstract: | We employ the Polyakov world-line path-integral version of QCD to identify and resum at leading perturbative order enhanced
radiative gluon contributions to the Drell-Yan type ( pair annihilation) cross-sections. We emphasize that this is the first time that world-line techniques are applied to cross-section
calculations.
