As the isospin filters of $I=0$ in the $\\pi\\Sigma$ channel and $I=1$ in the $\\pi\\bar{\\Lambda}$ channel, this process can be used to study the molecular structure of the $\\Lambda(1405)$ resonance, and to test the existence of the predicted states $\\Sigma(1380)$ and $\\Sigma(1430)$ with spin-parity $J^P=1/2^-$.
