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 ΛΛ 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)→K∗K and φ(2175)→KK dominate over the partial decay widths of η(2275)→VV(φφ,ωω,K∗K∗) and φ(2175)→VS(ωσ,K∗K0∗(800),φf0(980)) due to phase space and couplings.
