摘要：

The Lambda(c)(2940)(+) baryon with quantum numbers J(P) = 1/2(+) is considered as a molecular state composed of a nucleon and D* meson. We give predictions for the width of the radiative decay process Lambda(c)(2940)(+) -> Lambda(c)(2940)(+) + gamma in this interpretation. Based on our results we argue that an experimental determination of the radiative decay width of Lambda(c)(2940)(+) is important for the understanding of its intrinsic properties.
