P-3(0) study of meson decays in a chiral quark model

The strong decays of a meson into two mesons are studied in the framework o f the P-3(0) model. The meson wave functions are determined by means of a r ealistic chiral quark model constructed in the baryon sector and comparison is made with a traditional potential of "Coulomb + linear" type. Two diffe rent forms for the creation vertex are analyzed. A momentum dependent verte x is proved to be definitively superior. The chiral quark model provides an overall good description of all known transitions and gives results of rou ghly the same quality as those obtained from phenomenological quark-antiqua rk potentials.
