AnSU(2)effective lagrangian is extended to anSUL(3)⊗SUR(3)by including the vector and axial vector meson. With this effective lagrangian, electromagnetic form factors of charged pion and kaon are calculated in both time- and space-like regions. Good agreement with experimental data is obtained for those form factors. Decay widths of&rgr;→&pgr;&pgr;and&fgr;→K+K−are also calculated and shown to agree with experimental data very well. ©2001 American Institute of Physics.
