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.
