Abstract
The recent discovery of D s states suggests the existence of radial excitations. Our semirelativistic quark potential model succeeds in reproducing these states within one to two percent of accuracy compared with the experiments, D s0(2860) and D s * (2715), which are identified as 0+ and 1− radial excitations (n = 2). We also present calculations of radial excitations for B/B s heavy mesons. The relation between our formulation and the modified Goldberger-Treiman relation is also described.
