JP assignments of Λc+ baryons

  • The ``good" diquark is employed to study Λc+ baryons within a mass loaded flux tube model. The study indicates that all Λc+ 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.

JP assignments of Λc+ baryons

    Corresponding author: CHEN Bing,

Abstract: 

The ``good" diquark is employed to study Λc+ baryons within a mass loaded flux tube model. The study indicates that all Λc+ 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.
