Sequential hyperon decays in the reaction $e^{+}{e}^{-}\to {\Sigma }^0{\bar{\Sigma }}^0$

Abstract

We report on a study of the sequential hyperon decay ${\Sigma }^0\to \Lambda \gamma ;\Lambda \to p{\pi }^{-}$ 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 $e^{+}{e}^{-}\to {\Sigma }^0{\bar{\Sigma }}^0$. Cross-section distributions are calculated using the folding technique. We also study sequential decays of single-tagged hyperons.
