Towards the decays of ${\bar{N}}_X(1625)$ in the molecular picture

Abstract

In this talk, we firstly overview the experimental status of ${\bar{N}}_X(1625)$, which is an enhancement structure observed in $K^{-}\bar{\Lambda }$ invariant mass spectrum of $J/\psi \to p{K}^{-}\bar{\Lambda }$ process. Then we present the result of the decay of ${\bar{N}}_X(1625)$ under the two molecular assumptions, i.e. S-wave $\bar{\Lambda }{K}^{-}$ and S-wave ${\bar{\Sigma }}^0{K}^{-}$ molecular states. Several experimental suggestions for ${\bar{N}}_X(1625)$ are proposed.
