Abstract

It is demonstrated how the use of all existing experimental information on electric and magnetic nucleon form factors, described by the unitary and analytic (U) nucleon electromagnetic structure model in spacelike and timelike regions simultaneously, can provide numerical values of f^F,f^D,\phantom\rule4.pt0exand\phantom\rule4.pt0exf^S coupling constants in SU(3) invariant interaction Lagrangian of the vector-meson nonet with 1/2⁺ octet baryons. The latter, together with universal vector-meson coupling constants f_V, play an essential role in a prediction of 1/2⁺ octet hyperon electromagnetic form factor behaviors.
