Implications to $c\bar s$ assignments of $D_{s1}(2700)^\pm$ and $D_{sJ}(2860)$

Understand

Possible assignments of $D_{s1}(2700)^\pm$ and $D_{sJ}(2860)$ in the conventional quark model are analyzed.

• The study indicates that both the orbitally excited $c\bar s$ and the radially excited $c\bar s$ are possible.
• Some implications to these assignments are explored.
• If $D_{s1}(2700)^\pm$ and $D_{sJ}(2860)$ are the orbitally excited D-wave $1^- (j^P={3\over 2}^-)$ and $3^- (j^P={5\over 2}^-)$, respectively, another orbitally excited D-wave $2^-$ $D_s$, $D_{s2}(2800)$, is expected.
