NNLO corrections to charmless hadronic B decays
Guido Bell
We report on the status of the perturbative calculation in the QCD factorization framework to charmless hadronic B meson decays and present a compilation of available NNLO results.
B- -> pi- pi0/rho- rho0 to NNLO in QCD factorization
Guido Bell, Volker Pilipp
The approximate tree decays B- -> pi- pi0/rho- rho0 may serve as benchmark channels for testing the various theoretical descriptions of the strong interaction dynamics in hadronic…
NNLO vertex corrections in charmless hadronic B decays: Real part
Guido Bell
We compute the real part of the 2-loop vertex corrections for charmless hadronic B decays, completing the NNLO calculation of the topological tree amplitudes in QCD factorization.…
NNLO corrections to inclusive semileptonic B decays in the shape-function region
Guido Bell
We compute 2-loop QCD corrections to the hard coefficient functions which arise in the factorization formula for B -> X_u l nu decays in the shape-function region. Our calculation…
