2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/46214I review the treatment of high-energy QCD in Minkowski space, with an emphasis on factorization theorems as extensions of the operator product expansion. I discuss how the factorization properties of high-energy cross sections and amplitudes lead to evolution equations that resum large logarithms for two-scale problems.81 pages, 29 epsf figures.
