【 摘 要 】

The quark-level linear s model (LsM)is employed to compute a variety of electromagnetic and weak observables of light mesons,including pion and kaon form factors and charge radii, charged-pion polarizabilities,semileptonic weak K_l3 decay, semileptonic weak radiative pion and kaonform factors, radiative decays of vector mesons, and nonleptonic weak K_2p decay. The agreement of all these predicted observables withexperiment is striking. In passing, the tight link between the LsM andvector-meson dominance is shown. Some conclusions are drawn on the LsM inconnection with lattice and renormalization-group approaches to QCD.
