Abstract
A SU(2) effective lagrangian is extended to a $SU_{L}(3)\otimes SU_{R}(3)$ by including the vector and axial vector meson. With this effective lagrangian, electromagnetic form factors of charged pion and kaon are calculated. The pseudoscalar meson loops are taken into account. Good agreement with experimental data is obtained for those form factors. Decay widths of $\rho\to \pi\pi$ and $\phi\to K^{+}K^{-}$ are also calculated and shown to agree with experimental data very well.
