(Vector) Glueballs and Charmonium Decay Revisited

preprint1996arXivOpen access

Abstract

From the 0++0^{++} glueball candidate we argue that the 1−−1^{--} glueball OO to be near in mass to J/ψJ/ψ. This is supported by the recent null search for ψ′→ρπ,K∗Kˉψ^\prime \to ρπ, K^*\bar K, while absence of distortion in the energy scan of J/ψ→ρπJ/ψ\to ρπ indicates that ΓO≫ΓJ/ψΓ_O \gg Γ_{J/ψ}. OO may also play a role in the OZI violating pˉp→ϕγ,ϕπ\bar p p \to ϕγ, ϕπ production puzzle.
