摘要：

Recently, the Belle and LHCb Collaborations have measured the Lambda c+-> pK-pi+ invariant mass distribution, which shows a clear cusp structure around the eta Lambda threshold. In this work, we have analyzed this process by considering the triangle mechanism and the S-wave pseudoscalar meson-octet baryon interactions within the chiral unitary approach, which dynamically generates the Lambda(1670). Our results are in good agreement with the Belle measurements, which implies that the cusp structure around eta Lambda threshold could be associated with the Lambda(1670) with the molecular nature.
