Abstract

The SU(3)-symmetry breaking observed in the π+, K+ and K0 charge-radii or, equivalently, in the ρ{variant}ππ, ρ{variant}KK and φKK coupling constants is discussed in the Shifman-Vainshtein-Zakharov approach to three-point functions in the symmetrical subtraction configuration. The results are very stable and in good agreement with the data. © 1986 Springer-Verlag.
