Hyperon electromagnetic form factors in the timelike region

Johann Haidenbauer, Ulf-G. Meißner, Ling-Yun Dai

Electromagnetic form factors of hyperons ($\Lambda$, $\Sigma$, $\Xi$) in the timelike region, accessible in the reaction $e^{+}{e}^{-}\to \bar{Y}Y$, are studied. The focus is on energies close to the…
