强衰变$B_{s0} \to B_s π$和$B_{s1} \to B^*_s π$的光锥QCD求和规则

摘要:

本文利用光锥QCD求和规则计算了强耦合常数$g_{B_{s0} B_s η}$和$g_{B_{s1} B^*_s η}$。然后根据Dashen定理考虑小的$η-π^0$跃迁矩阵,得到了同位旋破坏过程$B_{s0}\to B_sη\to B_sπ^0$和$B_{s1}\to B_s^*η\to B_s^*π^0$的小衰变宽度。我们可以分别在不变的$B_s π^0$和$B^*_s π^0$质量分布中搜索奇底$(0^+,1^+)$介子$B_{s0}$和$B_{s1}$。

英文摘要:

In this article, we calculate the strong coupling constants $g_{B_{s0} B_s η}$ and $g_{B_{s1} B^*_s η}$ with the light-cone QCD sum rules. Then we take into account the small $η-π^0$ transition matrix according to Dashen's theorem, and obtain the small decay widths for the isospin violation processes $B_{s0}\to B_sη\to B_sπ^0$ and $B_{s1}\to B_s^*η\to B_s^*π^0$. We can search the strange-bottomed $(0^+,1^+)$ mesons $B_{s0}$ and $B_{s1}$ in the invariant $B_s π^0$ and $B^*_s π^0$ mass distributions respectively.
