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

Abstract

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