Interpretation of $D_{sJ}(2632{)}^{+}$, $D_{s1}(2700{)}^{\pm }$, $D_{sJ}^{\star }(2860{)}^{+}$ and $D_{sJ}(3040{)}^{+}$

Abstract

$D_s$ mesons are investigated in a semi-classic flux tube model where the spin-orbit interaction is taken into account. Spectrum of D-wave $D_s$ is predicted. The predicted spectrum is much lower than most previous predictions. Analysis of some $D_s$ candidates is made. $D_{sJ}(2632{)}^{+}$ may be a $1^{-}$ ($j^P={\frac{3}{2}}^{-}$ or $1^3{D}_1$) orbitally excited $D_s$ meson. $D_{s1}(2700{)}^{\pm }$ is very possible the first radially excited $1^{-}$ ($j^P={\frac{1}{2}}^{-}$ or $2^3{S}_1$) $D_s$ meson (the first radial excitation of $D_s^{\star \pm }(2112{)}^0$). $D_{sJ}^{\star }(2860{)}^{+}$ should be a $3^{-}$ ($j^P={\frac{5}{2}}^{-}$ or $1^3{D}_3$) orbitally excited $D_s$ meson, and $D_{sJ}(3040{)}^{+}$ is the first radially excited $1^{+}$ ($j^P={\frac{1}{2}}^{+}$) $D_s$ meson. Our conclusions are consistent with the most lately BaBar experiment.
