Description

The 'good' diquark is employed to study Λ+c baryons within a mass loaded flux tube model. The study indicates that all Λ+c baryons candidates in the 2008 review by the Particle Data Group (PDG) are well described in the mass loaded flux model. The quantum numbers JP of these Λc+ candidates are assigned. If Λc (2765)+ is an orbitally excited Λc+ , it is likely the JP = 3+/2 one. If Λc (2765)+ is an orbitally excited Σc, there ought to be another JP = 3+/2 Λc+ with mass ≅ 2770 MeV. In the model, there exists no JP = 1+/2 Λc+ (≅ 2700) predicted in existing literature. Λc(2940)+ is very possible the orbitally excited baryon with JP = 5-/2 (authors)
