Radiative Kaon Decay in Chiral Perturbation Theory

Abstract

We analyze the possibility of experimental investigation of new low-energy relations between the values of resonance masses in the meson form factors and the differential rate of radiative kaon decay $K^{+}\to {\pi }^{+}{e}^{+}{e}^{-}({\mu }^{+}{\mu }^{-})$ at the current level of the experimental precision. A set of arguments is listed in favour of that these relations can be a consequence of weak static interactions in the Standard Model.
