Abstract

The recent precise measurements of the e+eKSKL and e+eK+K cross sections and the hadronic spectral function of the τKKSντ 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.
