Remarks on the analysis of the reaction $e^{+}{e}^{-}\to {\Sigma }^0{\bar{\Sigma }}^0$

Abstract

We investigate roads for evaluating model-independent cross-section distributions for the sequential hyperon decay ${\Sigma }^0\to \Lambda \gamma ;\Lambda \to p{\pi }^{-}$ and its corresponding antihyperon decay. The hyperons are produced in the reaction $e^{+}{e}^{-}\to J/\psi \to {\Sigma }^0{\bar{\Sigma }}^0$. Cross-section distributions are calculated using the folding technique.
