Nondiffractive feature of γN→ρ±N with ρ-meson electromagnetic multipole moments
We investigate photoproduction of charged ρ off the nucleon using ρ(770)+π(140) Regge pole exchanges by considering the ρ-meson electromagnetic multipole moments. The significance of the Ward identity at the γρρ vertex is emphasized for current conservation in the process. Given π exchange with the...
