| 英文摘要 | In this paper we investigate the next-to-leading power contribution to the Bs -> gamma gamma and Bs -> gamma ee over bar decays from the strange quark mass effect with the dispersion approach which is QCD inspired and more predictive. We present the analytic expression of the quark mass contribution in the Bs -> gamma gamma and Bs -> gamma ee over bar decays, together with a new term that is missed in the previous study. We also evaluate the resolved photon contribution from the A-type amplitude in Bs -> gamma ee over bar decay. The numerical results of the strange quark mass contribution to the Bs -> gamma gamma decay is about 6% relative to the total branching ratio, while it is relatively small in the Bs -> gamma ee over bar decay due to the large resonance contribution. |
