Abstract

We report on a recent calculation of all Roper-related electromagnetic transtions form factors, covering the range of energies that next-to-come planned experiments are expected to map. Direct reliable calculations were performed, within a Poincar\'e covariant approach of the three-body bound-state problem, up to $Q^2/m^2_N$ =6; approximated then by applying the Schlessinger point method and the results eventually extended up to $Q^2/m^2_N\simeq$ 12 via analytic continuation.
