Canonical Interpretation of the D_{sJ}(2860) and D_{sJ}(2690)

Abstract

The spectrum and decay properties of radially excited $D_s$ states are examined in a new model. Good agreement is obtained with the properties of two recently announced $D_s$ mesons identified as $D_{s0}(2860)=c\bar{s}(2P)$ and $D_s^{\ast }(2690)=c\bar{s}$ as a possible mixture of $(2S;{}^3{S}_1)$ and $(1D;{}^3{D}_1)$. Searching for these mesons in B decays is advocated due to large predicted branching ratios.
