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

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 Poincaré covariant approach of the three-body bound-state pr...

Sumario: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 Poincaré covariant approach of the three-body bound-state problem, up to Q2=m2 N=6; approximated then by applying the Schlessinger point method and the results eventually extended up to Q2=m2 N '12 via analytic continuation
