D and D_s in mass loaded flux tube

Abstract

Heavy-light hadrons are studied in a mass loaded flux tube model. The study indicates that the dynamics of mesons and baryons containing a $c$ quark is well described by the mass loaded flux tube. The hypothesis of good diquark-antiquark degeneracy is found reasonable in heavy-light quark systems. The spectrum of charmed ($D$) and charmed strange ($D_s$) mesons is systematically computed. $D$ and $D_s$ in 1D multiplets are predicted to have lower masses in comparison with other theoretical predictions. The predicted masses of the $1^{-}(1^3{D}_1)$ and the $3^{-}(1^3{D}_3)$ $D_s$ agree well with those of recently observed $D_{s1}(2700{)}^{\pm }$ and $D_{sJ}(2860)$, respectively.
