Electromagnetic Form Factors of Hadrons in Dual-Large $N_c$ QCD

Abstract

In this talk, results are presented of determinations of electromagnetic form factors of hadrons (pion, proton, and $\Delta (1236)$) in the framework of Dual-Large $N_c$ QCD (Dual-$QC{D}_{\infty }$). This framework improves considerably tree-level VMD results by incorporating an infinite number of zero-width resonances, with masses and couplings fixed by the dual-resonance (Veneziano-type) model.
