2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44590We overview the issue of the power corrections to the parton model, mostly within the context of QCD sum rules. There are a few sources of the power corrections responsible for various qualitative effects. The basic idea that the power corrections are related to confining fields seems to be realized in case of $1/Q^2$ corrections which are dual to high orders of perturbation theory. The evidence comes from lattice studies of the confinement which allowed to identify the confining field configurations as monopoles and vortices. We comment also on the role of the condensate of dimension two, $<(A_μ^a)^2>_{min}$.8 pages, Latex file, Talk given at the QCD 05 International Conference (4-8th July 2005-Montpellier)High Energy Physics - PhenomenologyHigh Energy Physics - ExperimentHigh Energy Physics - LatticeHigh Energy Physics - TheoryNuclear Theorytext
