Abstract
The pi(+), K+ and (K) over tilde(0) charge radii and form factors in t he time-like region are analysed in an effective lagrangian context. T his lagrangian, written in terms of the pseudoscalar, vector and photo n fields, incorporates Vector Meson Dominance ideas and the main featu res of flavour symmetry. A reasonable description of the data is achie ved.
