    Symmetry-breaking parameters underU 3 ⊗U 3 andη-X mixing

    The symmetry-breaking parameters ofU 3 ⊗U 3 are found in a previous work to beb =c ∼ −1. They are used to evaluate theη-X mixing parameters. A generalη-X mixing scheme, in analogy with the ω-ϕ mixing, with two mi...

    Kt3 form factors,F K/F π and the symmetry-breaking parameter of the vacuum states

    Solving four sets of relations involving the Kt3 form factorsF ±(q 2) and the ratioF K/F π obtained in a previous paper, the values ofF +(0) andF K/F π are found to be functions of the symmetry-breaking parameter

    Current algebras, Kℓ3 form factors and the ratioF K/F π(*)

    Using the technique of the Bjorken limit, two constraint relations for Kℓ3 form factorsF ±(q 2) are derived. The possible forms of the form factorsF ±(q 2) are then determined through the Ward-Takahashi-type rela...

    On low-energy pion-pion scattering lengths

    The low-energy ππ scattering is treated within the framework of pole-dominance model. It is found that the contribution of the ρ-meson is as important as that ofS-waves, and that Weinberg’s amplitude of ππ scatte...

    Calculation of the decay rate of K 2 0 →π++π−+γ

    In K 2 0 →π++π−+γ, the decay can go either through a direct process or through an inner bremsstrahlung process. By applying the method of current algebras we es...

    Meson-baryon scattering in the spurion scheme of brokenU ℒ12-symmetry

    Meson-baryon scattering is discussed in the spurion scheme of brokenU ℒ12-symmetry. With the insertion of a momentum-dependent spurionS, there are now twelve amplitudes, instead of four in the strictU ℒ12-scheme....
