Description

The problem of electric and magnetic polarizabilities of pions is illustrated and their extraction from dispersion relations with one subtraction is given. Unambiguous determination of σ meson parameters and the decay of σ meson into two photons are carried out in order to determine the most realistic values of sum and difference of pion polarizabilities (Authors)
