Abstract

We have previously investigated joint $Λ \bar{Λ}$ $\Lambda \bar{\Lambda }$ decay in the reaction $e^{+} e^{-} \to γ Λ (\to p π^{-}) \bar{Λ} (\to \bar{p} π^{+})$ $e^+ e^- \rightarrow \gamma \Lambda (\rightarrow p\pi ^-) \bar{\Lambda }(\rightarrow \bar{p}\pi ^+)$ . The cross-section-distribution functions encountered were relativistically covariant and expressed in terms of scalar products of the four-momentum vectors of the particles involved. In the present, sequel investigation, we work instead in the $Λ \bar{Λ}$ $\Lambda \bar{\Lambda }$ rest system and with three-momentum scalars. In this configuration our results become directly comparable to those of others, including experiment.
