TLDR
In this article, the mixing effect on S*(975), epsilon (1300), and G(1590) was investigated by identifying the G1590 as a possible candidate for the scalar gluonium state, which enables one to explain the largeness of the G to eta eta rate relative to G to pi pi and G to KK.Abstract:

Masses, decays and mixings of gluonia in QCD
TL;DR: In this paper, the masses and decay widths of the gluonia using QCD spectral sum rules and low energy theorems were derived for the scalar and tensor sectors.
Journal ArticleDOI
Scalar mesons and scalar gluonium
TL;DR: In this paper, the mixing of scalar mesons with gluonium in the context of a potential model was investigated and the masses of the scalars and the branching ratios to ππ,KK, ηη and η η′ were calculated.

The octet model and its Clebsch-Gordan coefficients
TL;DR: In this article, the Wigner-Eckart theorem is applied to derive a general mass formula for the octets and the Gell-Mann-Okubo mass relation is used to satisfy the mesons.

Scalar mesons in the unitarized quark model
TL;DR: In this paper, it was shown that the scalar mesons can be seen as the unitarized remnants of conventional $q\overline{q}$ states, such as virtual two-meson states.

Is scalar gluonium observable
John Ellis,Jozef Lanik +1 more
TL;DR: In this article, the ITEP value of the gluon consensate was taken as an input, and it was shown that Γ(σ → ππ) ⋍ 0.6 GeV × (m σ 1 GeV ) 5, while m σ is undetermined.

Is the 0+ nonet respectable?
TL;DR: In this article, a scheme of assignments for the 0 + nonet is proposed with the S ∗ (1000) effect corresponding to resonance poles both on Sheet II and Sheet III, and with the ϵ located somewhere above 1100 MeV, e.g. at 1300 MeV.
