Hard spectator-scattering in B -> pi pi decays at NNLO
Martin BenekeSebastian Jager
文献摘要
We compute the 1-loop (NNLO) corrections to hard spectator-scattering in tree-dominated hadronic B decays. Depending on the values of hadronic input parameters the corrections are shown to have a significant impact on the B -> pi pi branching fractions.
