Abstract

In the special type of the quark model we obtain the ratioγ=hA/hV of the axial (hA) and vector (hV) form factors for the decays π → e ¯veγ and K → e¯veγ different from unity. The low-energy theorem, relating the electric polarizability of the charged pion απ with the ratioγ, is analyzed. It is shown thatγ< 1 corresponds to απ, calculated by accounting the contribution of the scalar mesonε(700) into the amplitude of the Compton effect on the pion. In the absence of theε(700) contribution we haveγ=1.
