Differential distributions in the π0π0γ system created in the annihilation channel of an electron–positron collision are considered. The energy fractions of the pions (Dalitz-plot) distribution are presented in a general form and in approximation of intermediate vector mesons (excited and ordinary ones). It is pointed out that in relevant experiments the generalized polarizability of the neutral pion can be measured. Numerical illustrations are presented.

In this chapter we develop the Glashow–Weinberg–Salam theory of electromagnetic and weak interactions based on the gauge group SU(2) × U(1). We show that the apparent difference in strength between the two interactions is due to the Brout–Englert–Higgs phenomenon which results in heavy intermediate vector bosons. The model is presented first for the leptons, and then we argue that the extension to hadrons requires the introduction of a fourth quark. We show that the GIM mechanism guarantees the natural suppression of strangeness changing neutral currents. In the same spirit, the need to introduce a natural source of CP-violation leads to a six quark model with the Cabibbo–Kobayashi–Maskawa mass matrix.

The full and differential widths of the decay [Formula: see text] are calculated in the framework of the extended Nambu–Jona-Lasinio model.The contributions of the subprocesses with the intermediate vector mesons [Formula: see text](770) and [Formula: see text](1450) are taken into account. The obtained results are in satisfactory agreement with the experimental data.

The processes [Formula: see text] and [Formula: see text] are calculated in the framework of the extended Nambu–Jona-Lasinio model. The intermediate vector mesons [Formula: see text], [Formula: see text], [Formula: see text] and their first radially excited states are taken into account. The obtained results are in satisfactory agreement with the experimental data. The predictions for the cross-sections of the reactions [Formula: see text], [Formula: see text] and [Formula: see text] were made.
