“…It is interesting to note that for the Y (4630) state, a relatively small cut off value is used, which seems more suitable for heavy hadron production processes [51][52][53]. As this value increases, the contributions of Y (4630) will become larger and the peak structure is also clear.…”

“…where the cut-off parameters Λ Y = 500 MeV for the Y (4630) state is used [51][52][53]. Then, according to the Feynman rules, the scattering amplitudes for the pp → Λ cΛc reaction can be obtained straightforwardly with the above effective Lagrangians, …”

We investigate the charmed baryon production reaction pp → ΛcΛc in an effective Lagrangian approach. Besides the t-channel D 0 and D * 0 mesons exchanges, the s-channel Y (4630) meson exchange is taken into account. For the total cross sections, the D 0 and D * 0 mesons provide minor background contributions, while the Y (4630) state gives a clear peak structure with the magnitude of 10 µb at center of mass energy 4.63 GeV. Basing on the results, we suggest that the reaction of pp → ΛcΛc can be used to search for the 1 −− charmonium-like Y (4630) state, and our predictions can be tested in future by thePANDA facility.

Abstract. The possible production of the neutral P c (4380) and P c (4450) in the J-PARC experiment is discussed. Different spin-parity assignments of the P c states are considered and differential cross sections of π − p → J/ψp are calculated. Moreover, the strong decays of P c → J/ψp are estimated based on a Σ cD * molecular scenario. Our results disfavor all the P− wave Σ cD * assignments, while favor the S − wave Σ cD * picture of the two P c states comparing to the experimental data. In addition, we also analyze the possible J P = 3/2 − state in Σ * cD and Σ * cD * pictures with heavy quark limit.
