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 $e^+e^-\to \bar YY$. 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.
