摘要：

Current algebra, dispersion relations, and the postulate of a partially conserved vector current with which we associate a strangeness-carrying scalar meson are employed to obtain the Kl3 form factors and other weak-decay parameters. The values f+(0)=0.96 and |FF|0.1 indicate that the SU(3) symmetry-breaking effect is negligibly small. The mass of the meson is found to be greater than 1300 MeV, with a very large width for the decay +K+. It is concluded that the existence of the meson as a physically observable particle is extremely doubtful. © 1968 The American Physical Society.
