Selected strong decays of $η(2225)$ and $ϕ(2170)$ as $Λ\barΛ$ bound states

Abstract

The strong decays of the two resonances $η(2225)$ and $ϕ(2170)$ are discussed for selected decay channels. The two resonances are considered as the $Λ\barΛ$ bound states in the molecular scenario. The phenomenological hadronic molecular approach is employed for the calculation of respective decay modes using effective Lagrangians. Our results show that the decay modes $η(2225)\to K^*K$ and $ϕ(2175) \to KK$ dominate over the partial decay widths of $η(2275)\to VV (ϕϕ, ωω, K^*K^*)$ and $ϕ(2175)\to VS (ωσ, K^*K^*_0(800), ϕf_0(980))$ due to phase space and couplings.
