文摘

Predicted masses of J^P=0⁺ and 1⁺ states of D_sJ and D by a 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/m_Q with m_Q heavy quark mass respecting heavy quark symmetry, have recently been confirmed by BaBar and Belle experiments within one percent accuracy.

In this Letter, decay modes of 0⁺ and 1⁺ states of B and B_s mesons are discussed using the predicted masses of this model.
