Recent discovery of D_sJ particles, which are considered to be a great trouble by experimentalists as well as theorists, had already been resolved by our potential model proposed some time ago by two of us (T.M. and T.M.), in which the Hamiltonian and wave functions are expanded in 1/(heavy quark mass) respecting heavy quark symmetry. Using our model, we explain how narrow states like D_sJ can be realized, predict properties of 0^+ and 1^+ states of B and B_s heavy mesons, and interpret how global SU(3) symmetry seems to be recovered for these 0^+ and 1^+ heavy mesons.
