Abstract
A new charm-strange meson, the , has recently been observed by the LHCb Collaboration which also determined the to have spin 3. One of the speculations about the previously observed is that it is the state. In this paper we reexamine the quark model properties and assignments of these three states in light of these new measurements. We conclude that the and are the and states respectively and the is the state. In addition to these three states there are another three excited states in this mass region still to be found, the and two states. We calculate the properties of these states and expect that LHCb has the capability of observing these states in the near future.
