Pace (Dipartimento d | | 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 $q^+>0$ decay in an interacting quark-antiquark pair,wich absorbs the initial pion and produces the pion in the final state. | | Source: | arXiv, hep-ph/0410031 | | Services: | Forum | Review | PDF | Favorites | |
