Dispersion relations and the $\Delta$ contributions into the amplitudes $M_{1+}^{3/2},E_{1+}^{3/2}$ from new VPI partial-wave analysis of pion photoproduction

I. G. Aznauryan

Within fixed-t dispersion relations the results of new VPI partial-wave analysis for the multipole amplitudes $M_{1+}^{3/2},E_{1+}^{3/2}$ are successfuly described, and the resonan…
