Description
In this paper we investigate the strong decays of the two newly observed bottom-strange mesons Bs1(5830) and Bs2*(5840) in the framework of the quark pair creation model. The two-body strong decay widths of Bs1(5830)0→B*+K- and Bs2*(5840)0→B+K-, B*+K- are calculated by considering Bs1(5830) to be a mixture between |1P1> and |3P1> states, and Bs2*(5840) to be a |3P2> state. The double pion decay of Bs1(5830) and Bs2*(5840) is supposed to occur via the intermediate state σ and f0(980). Although the double pion decay widths of Bs1(5830) and Bs2*(5840) are smaller than the two-body strong decay widths of Bs1(5830) and Bs2*(5840), one suggests future experiments to search the double pion decays of Bs1(5830) and Bs2*(5840) due to their sizable decay widths.
