The nucleon resonance structure from exclusive ${\pi }^{+}{\pi }^{-}p$ photo-/electroproduction off protons

V. D. Burkert, V. I. Mokeev, B. S. Ishkhanov

The results on the photo- and electroexcitation amplitudes of most nucleon resonances in the mass range up to 2.0 GeV determined from the CLAS experimental data on exclusive $π^+π^…
