World-line techniques for resumming gluon radiative corrections at the cross-section level

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/214868We 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 ($q\bar{q}$ pair annihilation) cross-sections. We emphasize that this is the first time that world-line techniques are applied to cross-section calculations.21 pages, using RevTeX. Three figures as EPS files. To appear in Eur. Phys. J.
