Strong decays $B_{s0} \to B_s π$ and $B_{s1} \to B^*_s π$ with light-cone QCD sum rules
Abstract
Description
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.
