Journal of High Energy Physics. Vol. 2011, n. 12, (2011). ISSN 1029-84791029-8479http://hdl.handle.net/10272/10495This brief note is devoted to a study of genuine non-perturbative corrections to the Landau gauge ghost-gluon vertex in terms of the non-vanishing dimension-two gluon condensate. We prove these corrections to give account of current SU(2) lattice data for the vertex with different kinematical configurations in the domain of intermediate momenta, roughly above 2-3 GeV. We pay special attention to the kinematical limit which the bare vertex takes for its tree-level expression at any perturbative order, according to the well-known Taylor theorem. Based on our OPE analysis, we also present a simple model for the vertex, in acceptable agreement with the lattice data also in the IR domain.engAn error occurred on the license name.An error occurred getting the license - uri.Nonperturbative EffectsSum RulesQCDLattice QCDjournal article10.1007/JHEP12(2011)018open access
