# Selected strong decays of $\eta(2225)$ and $\phi(2170)$ as $\Lambda \bar\Lambda$ bound states

## TL;DR

This paper investigates the strong decay behaviors of the resonances $ ext{eta}(2225)$ and $ ext{phi}(2170)$, proposing they are $ ext{Lambda}ar{ ext{Lambda}}$ molecular states, and uses a phenomenological approach to analyze their decay channels.

## Contribution

It introduces a molecular scenario for these resonances and calculates their decay modes using effective Lagrangians, providing insights into their structure and decay patterns.

## Key findings

- Decay modes $ ext{eta}(2225) o K^*K$ and $ ext{phi}(2170) o KK$ dominate.
- Decay modes involving vector and scalar mesons are suppressed due to phase space and couplings.
- Results support the molecular state interpretation of these resonances.

## Abstract

The strong decays of the two resonances $\eta(2225)$ and $\phi(2170)$ 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 $\eta(2225)\to K^*K$ and $\phi(2175) \to KK$ dominate over the partial decay widths of $\eta(2275)\to VV (\phi\phi, \omega\omega, K^*K^*)$ and $\phi(2175)\to VS (\omega\sigma, K^*K^*_0(800), \phi f_0(980))$ due to phase space and couplings.
