报告摘要: |
|
|
We completed the calculation of leading power contribution in doubly radiative B(Bs) \to \gamma \gamma decays, and considered the power suppressed contribution from local operators, nonlocal operators and power suppressed heavy quark field at tree level. We also considered the soft contribution using dispersion approach. There exists cancellation between different type of NLP contributions, while the power corrections are still more important than QCD corrections. |
