... moment and radius by incorporating various new developments not available at the time Ref.[1] was written. First, a new dispersion theoretical analysis of the nucleon form factors has been performed =-=[4]-=-. It improves upon the work of Höhler et al. [2] in various respects. These are the implementation of the constraints from perturbative QCD (pQCD) at large momentum transfer, the inclusion of the rece...

...uld be identified with the mass of the ω(1600) (denoted by S ′ in [4]). Furthermore, the symmetry breaking of the strong and electroweak interactions in the vector nonet has been considerably refined =-=[6]-=- leading to an improved value of the ωφ mixing angle ǫ. These are the ingredients we will use to update and sharpen the analysis of Jaffe. 2 Formalism It is straightforward to generalize Jaffe’s param...

However, as pointed out by Musolf =-=[7]-=-, the asymptotic behaviour of the strange vector formfactos plays an important role in such type of analyis as presented here or by Jaffe [1]. Given the assumptions used in our analysis, the large mom...

We remark that in the context of the Skyrme–type models, it is often stated that the large values of the resulting strange matrix–elements are an artefact of the SU(3) symmetric wave functions.
