Description

BaBar, Belle and CLEO have recently observed two narrow states in the D_s^*π⁰ and D_s^*γ channels, with masses of 2317 MeV and 2460 MeV, respectively. I discuss various interpretations proposed for these states; in particular, I consider the identification of the states with the low-lying positive parity doublet of the c\\bar{s} system.
