标题： Productions of bottom and bottom-strange mesons in pion and kaon induced reactions

摘要： 在本工作中，我们提出探讨在高能π介子和K介子诱导的质子靶反应中底夸克和底-奇夸克介子的产生。 截面是通过由重夸克极限和手征对称性构建的有效拉格朗日量来评估的。 我们的估计显示，在$P_\pi=80$ GeV 时，$B(5279)$、$B^\ast (5325)$、$B_0^\ast (5738)$、$B_1^\prime (5757)$、$B_1(5721)$和$B_2^\ast (5747)$生成过程的截面分别估计为$3.19 \sim 86.26$、$1.86\sim 51.29$、$0.87 \sim 24.25$、$0.84 \sim 23.14$、$162.35 \sim 4477.66$和$57.16 \sim 1604.43$ nb，其中不确定性来自模型参数。 此外，相应底-奇介子生成过程的截面非常相似。 此外，我们的估计表明，这些截面的比值几乎与模型参数无关。 特别是，属于同一双重态的状态相关的截面比值约为1，这与重夸克极限的预期一致。 与$T$双重态相关联的截面大约是与$S$双重态相关联的截面的两个数量级。 显示英文摘要

摘要： In the present work, we propose to explore the productions of the bottom and bottom-strange mesons in the high-energy pion and kaon-induced reactions on a proton target. The cross sections are evaluated with an effective Lagrangian constructed by the heavy-quark limit and chiral symmetry. Our estimations show that at $P_\pi=80$ GeV, the cross sections for $B(5279)$, $B^\ast (5325)$, $B_0^\ast (5738)$, $B_1^\prime (5757)$, $B_1(5721)$ and $B_2^\ast (5747)$ production processes are estimated to be $3.19 \sim 86.26$, $1.86\sim 51.29$, $0.87 \sim 24.25$, $0.84 \sim 23.14$, $162.35 \sim 4477.66$, and $57.16 \sim 1604.43$ nb, respectively, where uncertainties arise from the model parameter. In addition, the cross sections for the corresponding bottom-strange mesons production processes are very similar. Moreover, our estimations indicate that the ratios of these cross sections are almost independent on the model parameters. In particular, the cross-section ratios related to the states in the same doublets are of order one, which is consistent with the expectation of heavy-quark limit. The cross sections related to the states in the $T$ doublets are about two orders larger than those related to the states in the $S$ doublets.
