论文摘要
我们完成了非静态B-Meson衰变的QCD分解方法,以近代到领先顺序的QCD企鹅幅度的计算。这提供了QCD校正的最后一部分,以直接在QUARK扩展中引导功率直接CP不对称。
We complete the calculation of the QCD penguin amplitude at next-to-next-to-leading order in the QCD factorization approach to non-leptonic B-meson decays. This provides the last missing piece in the computation of the QCD correction to direct CP asymmetries at leading power in the heavy-quark expansion.
