新观测到的$B(5970)$及其自旋和奇异伴星的预言

Newly observed $B(5970)$ and the predictions of its spin and strange partners

Hao Xu, Xiang Liu, Takayuki Matsuki

摘要:

利用有效拉格朗日方法研究了新观测到的$B(5970)$介子的衰变行为,它被指定为$B$介子族中的$2^3S_1$态.更重要的是,我们预测了作为$B(5970)$的自旋和奇异伴子的$B(2^1S_0)$、$B_s(2^1S_0)$和$B_s(2^3S_1)$的部分和总衰变宽度的信息,这对今后寻找这些丢失态的实验有价值.

英文摘要:

Using the effective Lagrangian approach, we study the decay behavior of the newly observed $B(5970)$ meson, which is assigned as the $2^3S_1$ state in the $B$ meson family. What is more important is that we predict the information of the partial and total decay decay widths of $B(2^1S_0)$, $B_s(2^1S_0)$ and $B_s(2^3S_1)$ as the spin and strange partners of $B(5970)$, which is valuable to future experimental search for these missing states.
