Selected strong decays of $\eta (2225)$ and $\varphi (2170)$ as $\Lambda \bar{\Lambda }$ bound states

Abstract

The strong decays of the two resonances $\eta (2225)$ and $\varphi (2170)$ are discussed for selected decay channels. The two resonances are considered as the $\Lambda \bar{\Lambda }$ 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 $\eta (2225)\to K^{\ast }K$ and $\varphi (2175)\to KK$ dominate over the partial decay widths of $\eta (2275)\to VV(\varphi \varphi ,\omega \omega ,K^{\ast }{K}^{\ast })$ and $\varphi (2175)\to VS(\omega \sigma ,K^{\ast }{K}_0^{\ast }(800),\varphi f_0(980))$ due to phase space and couplings.
