摘要：

The Lambda(c)(2940)(+) baryon with quantum numbers J(P) = 1/2(+) is considered as a hadronic molecule composed of a nucleon and D* meson. We give predictions for the width of the strong three-body decay processes Lambda(c)(2940)(+) -> Lambda(c)(2286)(+) pi(+) pi(-) and Lambda(c)(2286)(+) pi(0) pi(0) in this interpretation. Upcoming experimental facilities like a Super B factory at KEK or LHCb might be able to provide data on these decay modes.
