Abstract

In this article, we calculate the strong coupling constants gBs0Bsηg_{B_{s0} B_s \eta} and gBs1Bsηg_{B_{s1} B^*_s \eta} with the light-cone QCD sum rules. Then we take into account the small ηπ0\eta-\pi^0 transition matrix according to Dashen's theorem, and obtain the small decay widths for the isospin violation processes Bs0BsηBsπ0B_{s0}\to B_s\eta\to B_s\pi^0 and Bs1BsηBsπ0B_{s1}\to B_s^*\eta\to B_s^*\pi^0. We can search the strange-bottomed (0+,1+)(0^+,1^+) mesons Bs0B_{s0} and Bs1B_{s1} in the invariant Bsπ0B_s \pi^0 and Bsπ0B^*_s \pi^0 mass distributions respectively.
