Mass Spectrum of a Meson Nonet is Linear
It is argued that the mass spectrum of a meson nonet is linear, consistent with the standard Gell-Mann–Okubo mass formula and leading to an extra Gell-Mann–Okubo mass relation for the masses of the isoscalar states. This relation is shown to hold with an accuracy of up to ∼3% for all well-established nonets. It also suggests a new qq̄ assignment for the scalar meson nonet. Bitnet: [email protected]...
متن کاملOn the mass relation of a meson nonet
It is pointed out that the omission of the effects of the transition between quarkonia or the assumption that the transition between quarkonia is flavor-independent would result in the inconsistent results for the pseudoscalar meson nonet. It is emphasized that the mass relation of the non-ideal mixing meson nonets should incorporate the effects of the flavor-dependent transition between quarko...
متن کاملHadronic Resonance Spectrum May Help in Resolution of Meson Nonet Enigmas
The identification of problematic meson states as the members of the quark model qq̄ nonets by using a hadronic resonance spectrum is discussed. The results favor the currently adopted qq̄ assignments for the axial-vector, tensor, and 1 F4 J PC = 4 meson nonets, and suggest a new qq̄ assignment for the Bitnet: [email protected] Bitnet: [email protected].

متن کاملIdentification of the glueballs and the scalar meson nonet of lowest mass 1
We discuss the theoretical expectations and phenomenological evidence for the lightest glueballs and the members of the meson nonet with quantum numbers J = 0. We reconsider the recent evidence for candidate states with masses below ∼1700 MeV, but include also the results from earlier phase-shift analyses. Arguments are presented to classify the scalars f0(980) and f0(1500) as members of the 0 ...
