Description
We present the determination of the nucleon’s Sachs electric form factor using the hadronic tensor formalism and verify that it is consistent with that from the conventional three-point function calculation. We additionally obtain the transition form factor from the nucleon to its first radial excited tate within a finite volume. Consequently, we identify the latter with the nucleon-to-Roper transition form factor
G_E*(Q^2), determine the corresponding longitudinal helicity amplitude S_1/2(Q^2) and compare our findings with experimental measurements, for the first time using the hadronic tensor formalism.
