| dc.description | We investigate the two-body decay modes $ρρ, ππ^{\ast}(1300)$ and $σσ$ of the $f_0(1500)$, all leading to the $4π$ decay channel, in a three-state mixing scheme, where the $f_0(1500)$ is a mixture of the lowest-lying scalar glueball with the nearby isoscalar states of the $0^{++} Q\bar{Q}$ nonet. In the leading order of this scheme, the decay mechanism of the $f_0(1500)$ proceeds dominantly via its quarkonia components, which can be described in the framework of the $^3P_0$ $Q\bar Q$ pair creation model. We predict the hierarchy of decay branching ratios B with $B(ρρ) ^{>}_{\sim} B(ππ) ^{>}_{\sim} B(σσ) > B(ππ^{\ast})$, providing a key signature for the proposed mixing scheme in this leading order approach. | |
