0^+ and 1^+ States of B and B_s Mesons

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.
