Abstract

The behaviour of the {Lambda}-hyperon electric and magnetic form factors is predicted within the modified three resonance with correct analytic properties and the asymptotic behaviopur predestinate by the quark model for baryons. The resonance couplings to {Lambda} are evaluated from the known couplings to nucleons by utilizing the SU(3) symmetry and normalization conditions for Dirac and Pauli for factors. The masses and widths of the considered vector mesons are fixed at the world averaged values. 13 refs.; 4 figs.
