Theoretical prediction of $\Lambda$, $\Sigma$, $\Xi$ hyperon magnetic form factors $|G_M^Y(t)|$ behaviours and also ratio $|G_E^Y(t)|/|G_M^Y(t)|$ in time-like region.

The advanced $Unitary\&Analytic$ hyperon EM structure model has been constructed and behaviors of the $|G^Y_M(t)|$ and the ratio $||G^Y_E(t)|/|G^Y_M(t)|$ are predicted in time-like region as functions of the total energy squared $t=W^2$ in the c.m. system of $Y \bar Y$, which are expected to be determined in measurements of the hyperon polar angle $\theta_Y$ in the $e^+e^- \to Y \bar Y$ processes.
