Abstract

In this article, we study the two-body strong decays of the bottom mesons with the heavy meson effective theory in the leading order approximation, and obtain all the analytical expressions of the decay widths of the light pseudoscalar mesons transitions among the S-wave, P-wave and D-wave bottom mesons. As an application, we tentatively assign the bottom meson B(5970) as the 2\rm S 1^-, 1\rm D 1^- and 1\rm D 3^- states, respectively, and calculate the decay widths of the B₁(5721), B₂(5747), B_s1(5830), B_s2(5840) and B(5970), which can be confronted with the experimental data in the future.
