Abstract
We study the pseudoscalar mesons in the framework of broken chiral SU(4) SU(4) symmetry when the symmetry‐breaking Hamiltonian, H~SB~, is taken as –(u~0~ + cu~8~ + du~15~) and the symmetry of the Hamiltonian is realized in Goldstone‐Nambu way. An interesting property of two chimeral SU(4) subgroups and the Goldstone nature of some of the pseudoscalar mesons in certain symmetry limits are exploited to obtain some mass relations and the ratio c/d.
