Abstract
In the context of the linear chiral SU(4) × 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) × 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 ( meson analog of such as , , etc., are computed with a choice of the symmetry-breaking term of (4, + (,4) type. Numerical analyses of the pseudoscalar-meson mass spectrum and the partial decay rates of are carried out.
