0 ++ trigluonium sum rules

We estimate the mass of the 0 ++ trigluonium associated to the g 3 f abc G μν a G νϱ b G ϱμ c gauge-invariant gluonic operator using QCD-duality sum rules. We also evaluate its mixing with the “standard” digluonium. Then, we conclude that one cannot interpret both the σ(0.5) and the G(1.6) as lowest...

Summary:We estimate the mass of the 0 ++ trigluonium associated to the g 3 f abc G μν a G νϱ b G ϱμ c gauge-invariant gluonic operator using QCD-duality sum rules. We also evaluate its mixing with the “standard” digluonium. Then, we conclude that one cannot interpret both the σ(0.5) and the G(1.6) as lowest mass gluonia.
