Abstract

In this article, we assume that the (0+,1+)(0^+,1^+) strange-bottom mesons are the conventional bsˉb\bar{s} mesons, and calculate the electromagnetic coupling constants dd, g1g_1, g2g_2 and g3g_3 using the light-cone QCD sum rules. Then we study the radiative decays Bs0BsγB_{s0}\to B_s^* \gamma, Bs1BsγB_{s1}\to B_s \gamma, Bs1BsγB_{s1}\to B_s^* \gamma and Bs1Bs0γB_{s1}\to B_{s0} \gamma, and observe that the widths are rather narrow. We can search for the (0+,1+)(0^+,1^+) strange-bottom mesons in the invariant Bsπ0B_s \pi^0 and Bsπ0B^*_s \pi^0 mass distributions in the strong decays or in the invariant BsγB_s^*\gamma and BsγB_s\gamma mass distributions in the radiative decays.
