英文摘要	We have performed a theoretical study on the process chi(c0)(1P) -> (Lambda) over bar Sigma pi, by taking into account the final-state interactions of pi Sigma and pi (Lambda) over bar based on the chiral unitary approach. As the isospin filters of I = 0 in the pi Sigma channel and I = 1 in the pi(Lambda) over bar 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(-). Our results show that there is a peak around 1350-1400 MeV and a cusp around the (K) over barN threshold in the pi Sigma invariant mass distribution, which should be the important feature of the molecular state Lambda(1405). We also find a peak around 1380 MeV and a cusp around the (K) over barN threshold in the pi(Lambda) over bar invariant mass distribution, which are associated to the Sigma(1380) and Sigma(1430) resonances.
