| Abstract: | ![]()
We present detailed numerical results for the pion space-like electromagnetic form factor obtained within a recently proposed model of the pion electromagnetic current in a confining light-front QCD-inspired model. The model incorporates the vector meson dominance mechanism at the quark level, where the dressed photon with q+ > 0 decays in an interacting quark-antiquark pair, which absorbs the initial pion and produces the pion in the final state. |
