Light-front quark model consistent with Drell-Yan-West duality and quark counting rules

From the matching of soft-wall AdS/QCD and light-front QCD for electromagnetic form factors of hadrons with arbitrary twist, we derive an effective light-front wave function (LFWF). The scale at which such matching is performed is set as an initial scale. Together with the LFWF, we also obtain expressions for parton distribution functions (PDFs) and generalized parton distributions (GPDs) at this scale. Doing the hard evolution of PDFs and GPDs,...
