Review of Recent Measurements of Meson and Hyperon Form Factors

Abstract

A review of recent precision measurements of the electromagnetic form factors of the mesons, pion and kaon, and the hyperons, $\Lambda^0$, $\Sigma^0$, $\Sigma^+$, $\Xi^-$, $\Xi^0$, $\Omega^-$, at large timelike momentum transfers is presented. Evidence is found for diquark correlations in $\Lambda^0$, $\Sigma^0$ hyperons.
