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

Understand

$D_s$ 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.
