Possible candidate of 0^+ s\bar{s}s\bar{s} state
Abstract
The possibility of the $0^+$ $ηη$ resonance $f_0(2100)$ as a candidate of the $Q^2\bar{Q}^2$ state $C^{ss}(36)$ is explored. The $ηη$ channel of $f_0(2100)$ is the dominant decay mode, $ηη'$ channel has less decay rate, the decay rate of the $η'η'$ channel is very small. The $ππ,\;K\bar{K},\;4π$ modes are at next leading order in $N_C$ expansion. Other possible decay modes are discussed.
