Abstract:
A classic mass loaded flux tube model and the diquark picture are employed to explore both mesons and baryons. The spectrum of A<'+><,c> baryons and D<,s> mesons is systematically obtained. The spin-orbit interaction in Ds was simplified as and (L→·S→) coupling.The spin-orbit interaction in Ac was simplified as a (J1→·Jc→) coupling. The predicted masses are consistent with the latest experiments.
