Scalar-Pseudoscalar scattering and pseudoscalar resonances

الأصل · EN

The interactions between the f₀(980) and a₀(980) scalar resonances and the lightest pseudoscalar mesons are studied. We first obtain the interacting kernels, without including any ad hoc free parameter, because the lightest scalar resonances are dynamically generated. These kernels are unitarized, giving the final amplitudes, which generate pseudoscalar resonances, associated with the K(1460), π(1300), π(1800), η(1475) and X(1835). We also consider the exotic channels with I=3/2 and Iᵍ=1+ quantum numbers. The former could be also resonant in agreement with a previous prediction.
