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 similar or equal to 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.

Abstract
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 similar or equal to 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.File in questo prodotto:
