Entanglement in joint $\Lambda \bar{\Lambda }$ decay; cont

Abstract

We have previously investigated joint $\Lambda \bar{\Lambda }$ decay in the reaction $e^{+}{e}^{-}\to \gamma \Lambda (\to p{\pi }^{-})\bar{\Lambda }(\to \bar{p}{\pi }^{+})$. 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 show that by working with three-momentum scalars instead results could possibly become more transparant.
