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, g1, g2, and g3 using the light-cone QCD sum rules. Then we study the radiative decays Bs0 → Bs* γ, Bs1→ Bs* γ, Bs1 → Bs* γ, and Bs1→ Bs0 γ, and observe that the widths are rather narrow. We can search for the (0+,1+) strange-bottom mesons in the invariant Bs π0 and Bs0 mass distributions in the strong
decays or in the invariant Bs*γ and Bsγ mass distributions in the radiative decays.

Key words
