【 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 Kl3 decay, semileptonic weak radiative pion and kaonform factors, radiative decays of vector mesons, and nonleptonic weak K2p 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.
