QCD Calculations of Radiative B Decays
Mikolaj Misiak
The current status of B -> Xs gamma decay rate calculations is summarized. Missing ingredients at the NNLO level are listed. The global normalization factor and non-perturbative ef…
Collider aspects of flavour physics at high Q
T. Lari, L. Pape, W. Porod +105
This review presents flavour related issues in the production and decays of heavy states at LHC, both from the experimental side and from the theoretical side. We review top quark…
NNLO QCD corrections to B -> X_s gamma
M. Misiak
Current status of the NNLO QCD corrections to B -> X_s gamma is reviewed. The calculations include three-loop matching conditions, four-loop anomalous dimensions as well as two- an…
NNLO QCD corrections to the B -> X_s gamma matrix elements using interpolation in m_c
Mikolaj Misiak, Matthias Steinhauser
One of the most troublesome contributions to the NNLO QCD corrections to B -> X_s gamma originates from three-loop matrix elements of four-quark operators. A part of this contribut…
Estimate of BR(B -> X_s gamma) at O(alpha_s^2)
M. Misiak, H. M. Asatrian, K. Bieri +14
Combining our results for various O(alpha_s^2) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next…
Three-Loop Mixing of Dipole Operators
Martin Gorbahn, Ulrich Haisch, Mikolaj Misiak
We calculate the complete three-loop O(alpha_s^3) anomalous dimension matrix for the dimension-five dipole operators that arise in the Standard Model after integrating out the top…
