Two-loop non-leptonic penguin amplitude in QCD factorization

Two-loop non-leptonic penguin amplitude in QCD factorization

Abstract 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-q...
