Abstract

The recent precise measurements of the e + e − → K + K − and e + e − → KS KL cross sections and the hadronic spectral function of the τ − → K − K S ν τ 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.
