摘要：

The new SU(3) nonet mass formula 2M(2)(s (s) over bar) + 3M(2)(n (n) over bar, I = 1) = 4M(2)(s (n) over bar) + M-2(n (n) over bar, I = 0) (n = u, d), obtained in our previous paper by using Regge phenomenology, is rederived for the pseudoscalar and scalar mesons in the Nambu-Jona-Lasinio model with instanton-induced interaction and applied to the problem of the correct qq assignment for the scalar meson nonet. The results strongly favor the masses of the scalar isoscalar mostly octet and mostly singlet states in the vicinity of 1.45 and 1.1 GeV, respectively. (C) 1998 Elsevier Science B.V.
