Polarization Response Functions in Kaon Electroproduction

The electroproduction of kaons on the nucleon is shown to be an ideal tool to extract electromagnetic form factors of strange mesons and hyperons. Longitudinal n(e,e'K0)Lambda cross sections are found to be sensitive to the K0 form factor, while sensitivity to the Lambda magnetic form factor can be seen in recoil-beam double polarization observables. The KK*\gamma transition form factor could be extracted by measuring transverse response functions in the K-Sigma channels.
