Abstract

We report on a recent calculation of all Roper-related electromagnetic\ntranstions form factors, covering the range of energies that next-to-come\nplanned experiments are expected to map. Direct reliable calculations were\nperformed, within a Poincar 'e covariant approach of the three-body bound-state\nproblem, up to Q²/m²_N=6; approximated then by applying the Schlessinger\npoint method and the results eventually extended up to Q²/m²_N\≃12 via\nanalytic continuation.\n
