英文摘要	In this paper, we present the full Lagrangian of mesons ( pseudoscalars, vectors and axial-vectors) to O(p(4)) by using the explicit global chiral symmetry and hidden local symmetry in the chiral limit. In this approach, we see that there are many other terms besides the usual eleven terms given in the literature from a hidden local symmetry approach. In particular, there are some terms in our full results which are important for understanding the vector meson dominance and pi-pi scattering and providing consistent predictions on the decay rates of a(1) --> gammapi and a(1) --> rhopi as well as for constructing a consistent effective chiral Lagrangian with chiral perturbation theory. It is likely that the structures of the effective chiral Lagrangian for O( p 4) given in the literature by using hidden local symmetry are incomplete and consequently the resulting couplings are not reliable. We examine the issue that the more general effective chiral Lagrangian given in the present paper can provide more consistent predictions for the low energy phenomenology of the rho-a(1) system and result in more consistent descriptions on the low energy behavior of light flavor mesons.
