摘要：

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 (s) over bar (2P) and D-s*(2690) = c (s) over bar as a possible mixture of (2S; S-3(1)) and (1D; D-3(1)). Searching for these mesons in B decays is advocated due to large predicted branching ratios. (c) 2007 Elsevier B.V. All rights reserved.
