Abstract
The recent precise measurements of the e+e– → KSKL and e+e– → K+K– cross sections and the hadronic spectral function of the τ– → K–KSντ decay are used to extract the isoscalar and isovector electromagnetic kaon form factors and their relative phase in a model-independent way. The experimental results are compared with a fit based on the vector-meson-dominance model.
