Using the effective Lagrangian approach, we study the decay behavior of the newly observed B(5970) meson, which is assigned as the 2(3)S(1) state in the B meson family. A more important prediction is the detailed information of the partial and total decay widths of B(2(1)S(0)), B-s(2(1)S(0)), and B-s(2(3)S(1)) as the spin and strange partners of B(5970), which can be tested in future experimental searches for these missing states.
