| 摘 要： | In order to make a further confirmation of the assignments of the excited bottom and bottom-strange mesons B1(5721),B2^*(5747),Bs1(5830)and Bs2^*(5840)and identify possible assignments of BJ(5840)and BJ(5970),we study the strong decay of these states with the 3P0 decay model.Our analysis supports the assignments of B1(5721)and B2*(5747)as the 1P'1 and 1^3P2 states,and Bs1(5830)and Bs2^*(5840)as the strange partners of B1(5721)and B2^*(5747).Besides,we tentatively identify the recently observed BJ(5840)and BJ(5970)as the 2^3S1 and 13D3 states.It is noted that these conclusions need further confirmation by measurements of the decay channels BJ(5840)→Bπand BJ(5970)→Bπ.

| Abstract: | In order to make a further confirmation of the assignments of the excited bottom and bottom-strange mesons B1（5721）, B2*（5747）, Bs1（5830） and Bs2*（5840） and identify possible assignments of BJ（5840） and BJ（5970）,we study the strong decay of these states with the 3P0 decay model. Our analysis supports the assignments of B1（5721） and B2*（5747） as the 1P′1 and 13P2 states, and Bs1（5830） and Bs2*（5840） as the strange partners of B1（5721）and B2*（5747）.. Besides, we tentatively identify the recently observed BJ（5840） and BJ（5970） as the 23S1 and 13D3 states. It is noted that these conclusions need further confirmation by measurements of the decay channels BJ（5840） → Bπ and BJ（5970） → Bπ. |
