Abstract

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.
