Pion and kaon electromagnetic form factors and their related decays in an SU[sub L](3)⊗SU[sub R](3) effective lagrangian

Abstract

An SU(2) effective lagrangian is extended to an SUL(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 ρ→ππ and φ→K+K− are also calculated and shown to agree with experimental data very well.
