Once more on electromagnetic form factors of nucleons in extended vector meson dominance model

TL;DR

This paper presents an extended vector meson dominance model that accurately describes nucleon electromagnetic form factors across space-like and time-like regions with minimal free parameters.

Contribution

The paper introduces a novel extended vector meson dominance model that aligns with quark counting rules and fits experimental data effectively.

Findings

Good fit to experimental form factors in space-like region

Reasonable results obtained in time-like region

Model uses minimal free parameters

Abstract

Extended vector meson dominance model, that allows to describe the electromagnetic form factors of nucleons obeying the asymptotic quark counting rule prescriptions and contains the minimal number of free parameters, is presented. We get a reasonable fit of form factors over experimentally available space-like region of momentum transfer and get also reasonable results in the time-like region.
