Interpretation of SAMPLE and HAPPEX Experimental Results on Strange Nucleon Form Factors

Abstract

A behaviour of strange nucleon form factors is predicted by means of Jaffe's idea about the relations of $\omega$ and $\varphi$ vector-meson coupling constant ratios. Its application to a specific eight-resonance unitary and analytic model of nucleon electromagnetic structure, describing also the time-like nucleon electromagnetic form factor data, explains the positive central values from recent SAMPLE and HAPPEX experiments.
