Strong decay of Λc(2940) as a 2P state in the Λc family

Considering the mass, parity and D-0 p decay mode, we tentatively assign the Lambda(c)(2940) as the P-wave states with one radial excitation. Then, via studying the strong decay behavior of the Lambda(c) (2940) within the P-3(0) model, we obtain that the total decay widths of the Lambda(c1)(1/2(-), 2P) and Lambda(c1)(3/2(-), 2P) states are 16.27 and 25.39 MeV, respectively. Compared with the experimental total width 27.71(-6.0)(+8.2) +/- 0.9(-10.4)(+5.2) MeV measured by LHCb Collaboration, both assignments are allowed, and the J(P) = 3/2(-)assignment is more favorable. Other lambda-mode Sigma(c)(2P) states are also investigated, which are most likely to be narrow states and have good potential to be observed in future experiments.
