Radially excited pseudoscalar states and the problem of the l(1440) meson
Filippov A. T.
A model of strong mixing in a radially excited pseudoscalar nonet is proposed by analogy with mixing in the ground nonet. Comparison of the predicted mass formulas and the relations between the probabilities for the production of isoscalar particles with experimental data on the resonances ττ'(1205), ζ (1275), and t(1440) indicates a possible mixing of these states in a single radial nonet.
