TL;DRAbstract

The use of a form factor which is invariant with respect to the spectrum-generating SU(3) leads to a definition for the strangeness-changing suppression factor for ${K}_{{l}_{3}}$ decay which is numerically equal to the strangeness-changing suppression factor for ${K}_{{l}_{2}}$ decay and close to $\frac{{m}_{\ensuremath{\pi}}}{{m}_{K}}$. It also predicts the electromagnetic radius of the pseudoscalar mesons in terms of ${\ensuremath{\lambda}}_{+}$.
