Form factors for the Nucleon-to-Roper electromagnetic transition at large Q2

José Rodríguez-Quintero, Daniele Binosi, Chen Chen, Ya Lu, Craig D. Roberts, Jorge Segovia
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 Poincare covariant approach of the three-body bound-state problem, up to Q2/m2N=6; approximated then by applying the Schlessinger point method and the results eventually extended up to Q2/m2N=12 via analytic continuation.
