Radiative decays of the $(0^+,1^+)$ strange-bottom mesons

Abstract

In this article, we assume that the $(0^+,1^+)$ strange-bottom mesons are the conventional $b\bar{s}$ mesons, and calculate the electromagnetic coupling constants $d$, $g_1$, $g_2$ and $g_3$ using the light-cone QCD sum rules. Then we study the radiative decays $B_{s0}\to B_s^* γ$, $B_{s1}\to B_s γ$, $B_{s1}\to B_s^* γ$ and $B_{s1}\to B_{s0} γ$, and observe that the widths are rather narrow. We can search for the $(0^+,1^+)$ strange-bottom mesons in the invariant $B_s π^0$ and $B^*_s π^0$ mass distributions in the strong decays or in the invariant $B_s^*γ$ and $B_sγ$ mass distributions in the radiative decays.
