  "abstract": "We have performed a theoretical study of the process $\\chi_{c0}(1P)\\to \\bar{\\Lambda}\\Sigma\\pi$, by taking into account the final state interactions of $\\pi\\Sigma$ and $\\pi\\bar{\\Lambda}$ based on the chiral unitary approach, and also the intermediate resonance $\\Sigma(1380)$ in $\\pi\\bar{\\Lambda}$ system. As the isospin $I=0$ filter of the $\\pi\\Sigma$ channel, this reaction can be used to search for the two $\\Lambda(1405)$ states. In addition, since this process also filters the isospin $I=1$ of the $\\pi\\bar{\\Lambda}$ channel, the shape of the $\\pi\\bar{\\Lambda}$ mass distribution of this process can be used to test the existences of the $\\Sigma(1380)$ with $J^P=1/2^-$ and the baryon state around the $\\bar{K}N$ threshold, with $J^P=1/2^-$, strangeness $S=1$, and isospin $I=1$, predicted in the chiral unitary approach.",
