The large data sample recorded by the Belle experiment at the KEKB asymmetric-energy $e^{+} e^{-}$ collider is very useful for studying light baryons or mesons. We report the observation of $\Omega(2012)^{-} \to \Xi(1530)^0 K^-$ as well as of a narrow structure in $\Lambda^{+}_{c} \to p K^-\pi^+$. We also discuss about the determination of resonant parameters of $\phi(1680)$ using the...

70. Interpretation of the $\eta_1(1855)$ as a $K\bar{K}_1(1400)+ c.c.$ molecule

An exotic state with $J^{PC}=1^{-+}$, denoted by $\eta_1(1855)$, was observed by BESIII collaboration recently in $J/\psi \to \gamma \eta\eta^\prime$. The fact that its mass is just below the threshold of $K\bar{K}_1(1400)$ stimulates us to investigate whether this exotic state can be interpreted as a $K\bar{K}_1(1400)+ c.c.$ {molecule or not}. Using the one boson exchange model, we show that...
