摘要：

An improved update of the structure and decays of rho(0), omega and phi mesons based on a chiral SU(3) Lagrangian, including anomaly terms is presented. We demonstrate that a consistent and quantitatively successful description of both pion and kaon electromagnetic form factors can be achieved. We also discuss the e(+)e(-) --> pi(+)pi(0) pi(-) cross section, the Dalitz decay omega --> pi(0) mu(+)mu(-) and aspects of rho(0) omega and omega phi mixing. Relations to previous versions of the Vector Meson Dominance model will be examined.
