Abstract

Electromagnetic form factors of hadrons for timelike momentum transfers can be measured by particle-antiparticle annihilation into hadron-antihadron pairs. We have made the world's first high precision measurements of timelike form factors of π and K mesons, and ground states of the baryons, protons, and the hyperons Λ0, Σ0, Σ+, Σ0, Σ-, Ω - at the high momentum transfers of 14.2 and 17.4 GeV2. Limitations of perturbative QCD are revealed, and evidence is presented for the effects of diquark correlations in Λ0 and Σ0.
