Holographic Oddballs

Understand

The spectrum of the glueball with $J^{PC}=0^{--}$ is computed using different bottom-up holographic models of QCD.

• The results indicate a lowest-lying state lighter than in the determination by other methods, with mass $m \simeq 2.8$ GeV.
• The in-medium properties of this gluonium are investigated, and stability against thermal and density effects is compared to other hadronic systems.
• Production and decay modes are identified, useful for searching the $J^{PC}=0^{--}$ glueball.
