New resonances in the linear chiral SU(4) x SU(4) model
In the context of the linear chiral SU(4) x SU(4) model, we study a Lagrangian of 16 pseudoscalar and 16 scalar fields interacting by means of the most general nonderivative chiral-SU(4) x SU(4) -invariant interaction and any particular symmetry-breaking term. The three-point and four-point coupling constants in the model can simply be related to masses in the system. As an application, partial decay rates of eta'' (0/sup -/ meson analog of psi) such as eta'' ..-->.. K + K-bar + ..pi.., eta'' ..-->.. eta + ..pi.. + ..pi.., etc., are computed with a choice of the symmetry-breaking term of (4,4*) + (4*,4) type. Numerical analyses of the pseudoscalar-meson mass spectrum and the partial decay rates of eta'' are carried out.
