Abstract

This paper is focused on two issues: the Kπspectrum near threshold - the kappa problem -, and the piπspectrum between 1.2 and 1.5 GeV/(c²) -- the f₀(1370) problem. Both problems will be analysed from the perspective of the D meson decays, with some additional information from τ and B decays.
