Abstract

We report on a study of the sequential hyperon decay Σ0Λγ;Λpπ\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+eΣ0Σˉ0e^+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.
