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