Towards Resolution of the Scalar Meson Nonet Enigma
نویسنده
چکیده
By the application of a linear mass spectrum to a composite system of both the pseudoscalar and scalar meson nonets, we find three relations for the masses of the scalar states which suggest the qq̄ assignment for the scalar meson nonet: a0(1320), K ∗ 0 (1430), f0(1500) and f ′ 0(980).

Towards Resolution of the Scalar Meson Nonet Enigma II.Gell-Mann–Okubo Revisited
The new SU(3) nonet mass formula 2M2(ss̄)+3M2(nn̄, I = 1) = 4M2(sn̄)+ M2(nn̄, 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 qq̄ assignment for the scalar meson nonet. The results strongly favor the masses of...

We show that two nonets and a glueball provide a consistent description of data on scalar mesons below 1.7 GeV. Above 1 GeV the states form a conventional qq̄ nonet mixed with the glueball of lattice QCD. Below 1 GeV the states also form a nonet, as implied by the attractive forces of QCD, but of more complicated nature. Near the center they are (qq)3̄(q̄q̄)3 in S-wave, with some qq̄ in P-wave, but ...

We study whether light scalar meson nonet can survive in large values of Nc through observing how scattering amplitudes behave as Nc increases from 3 within a unitarized chiral approach. We obtain the result that vector mesons such as ρ and K∗ survive as narrow width resonances, but all of the scalar meson nonet below 1 GeV fade out as Nc exceeds a rather small number about 6.
