Electromagnetic form factors of hyperons in the timelike region: A short review

Abstract

We review recent experimental and theoretical results for the electromagnetic form factors of hyperons (Y) in the timelike region, accessible in the reactions $e^{+}{e}^{-}\to \bar{Y}Y$. Specifically, we focus on the final states $\bar{\Lambda }\Lambda$, $\bar{\Lambda }{\Sigma }^0$/${\bar{\Sigma }}^0\Lambda$, $\bar{\Sigma }\Sigma$, $\bar{\Xi }\Xi$, and $\bar{\Omega }\Omega$. The ${\bar{\Lambda }}_c{\Lambda }_c$ system is also discussed.
