First Measurements of Form Factors of Pion, Kaon, Proton, and Hyperons for the Highest Timelike Momentum Transfers

[摘要] Results of recent precision measurements of the electromagnetic form factors of the pion, kaon, proton, and the hyperons, Λ0, Σ0, Σ+, Ξ-, Ξ0, Ω-, at large timelike momentum transfers are presented. Evidence is found for diquark correlations in Λ0, Σ0hyperons.
