Abstract
The hadrodynamics of the instantaneous weak interactions (IWI) in Standard Model is considered supposing the resonance nature of the chiral hadronization of quark currents in QCD. Exploiting this supposition and QCD symmetries the IWI mechanism of enhancement of the K+ --> pi+ transition probability is obtained and relations between electroweak meson form factors and the amplitudes of the processes K+ --> pi+ e+ e-(mu+ mu-,nu anti-nu) and K+ pi- --> e+ e-(mu+ mu-, nu anti-nu) are estalished. We estimate possible parameters of the K+ --> pi+ e+ e- decay rate in NA48/2 CERN experiment using the chiral perturbation theory.
