## Abstract

We report on a study of the sequential hyperon decay $\Sigma^0\rightarrow\Lambda \gamma;\Lambda\rightarrow p\pi^- $ and its corresponding anti-hyperon decay. We derive a multi-dimentional and model-independent formalism for the case when the hyperons are produced in the reaction $e^+e^-\rightarrow\Sigma^0\bar{\Sigma}^0$. Cross-section distributions are calculated using the folding technique. We also study sequential decays of single-tagged hyperons.
