Description

The advanced $\Lambda$, $\Sigma$, $\Xi$ hyperon Unitary and Analytic electromagnetic structure models are constructed explicitly and behaviours of $|G_M^H(t)|$ and ratios $|G_E^H(t)|/|G_M^H(t)|$ are predicted in time-like region as functions of the total energy squared $t=W^2$ in the c.m. system of $H\bar H$, which will be found out in intended
measurements of the $\Lambda$, $\Sigma$, $\Xi$ hyperon polar angle $\Theta_H$ distributions $F(\cos\Theta_H)$ in $e^+e^-\to H\bar H$ processes.
