Abstract
In the framework of unitary and analytic model of nucleon electromagnetic structure, the values of nucleon coupling constants are received from the fit of nucleon data. With the help of SU(3) relations the coupling constants of other hyperons, i.e., Î, Σ+, Σ0, Σâ, Î0, Îâ are calculated. The values of hyperon coupling constants are used to predict the behaviour of hyperon electromagnetic form factors and corresponding cross sections e+eââ hyperon-antihyperon.
