“…We assume the glueball dominance of quarkonium mixing, viz., there is no direct quarkonium-quarkonium mixing, and the qq ↔ q ′q′ transition is dominated by the glueball with the corresponding quantum numbers in the intermediate state [12].…”

We provide the first explanation of the counter-intuitive scalar glueball couplings to pseudoscalar mesons found in lattice QCD and predict hitherto uncalculated decay modes. Significant a 1 π and (ππ) S (ππ) S couplings are found. We demonstrate the equivalence of linear and quadratic mass matrices for glueballquarkonium mixing. The equivalence of formalisms which deal with a glueballquarkonium basis and only a quarkonium basis is demonstrated. We show that the f 0 (1500) is not the heaviest state arising from glueball-quarkonium mixing for a glueball mass consistent with lattice QCD. The masses and couplings of scalar mesons, as well as their valence content, are calculated.

“…To accomplish it, this glueball must have very special, if not unnatural, properties [30]: It is nearly degenerate with J/ψ with a quite narrow width for an object of mass ∼ 3 GeV and decays predominantly into 1 − 0 − . Later Hou [31] relaxed the constraint on the ρπ branching to argue that such a glueball was not yet ruled out by the search of the BES Collaboration [32].…”

Possible hadronic excess in ψ(2S) decay and the ρπ puzzle

We study the so-called ρπ puzzle of the ψ(2S) decay by incorporating two inputs; the relative phase between the one-photon and the gluonic decay amplitude, and a possible hadronic excess in the inclusive nonelectromagnetic decay rate of ψ(2S). We look into the possibility that the hadronic excess in ψ(2S) originates from a decay process of long-distance origin which is absent from the J/ψ decay. We propose that the amplitude of this additional process happens to nearly cancel the short-distance gluonic amplitude in the exclusive decay ψ(2S) → 1 − 0 − and turn the sum dominantly real in contrast to the J/ψ decay. We present general consequences of this mechanism and survey two models which might possibly explain the source of this additional amplitude.

“…Among various solutions attempting to resolve the "ρπ anomaly" in charmonium decays [1] [2], the resonance enhancement model, as proposed by Hou and Soni [3] and later generalized by Brodsky, Lepage, and Tuan [4], requires the existence of a vector glueball O [5]. Since both the rest energy m O − i Γ O /2 and the mixing amplitudes f Oψ , f Oψ ′ with charmonium J/ψ and ψ ′ are needed in the analysis of "ρπ anomaly " [6], it is necessary to study these issues within a hadronic model and henceforth provide some quantitative information. A naive approach [7] based on a constituent model of gluons [8] was used earlier to study the glueball spectrum in the pure Yang-Mills gauge theory.…”

We study the mixing angle θ Oψ and mixing amplitude f Oψ of J/ψ and vector glueball O, in the framework of potential models of heavy quarks and constituent gluons. While the state vectors of J/ψ and O are constructed from the wave functions of few-body Schroedinger equations, the mixing dynamics is governed by perturbative QCD. We obtain a value of the mixing angle of | tan θ Oψ | ≈ 0.015 and the mixing amplitude of |f Oψ (m 2 Oψ )| ≈ 0.008 GeV 2 , which is compatible with phenomenological analysis.
