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…
Enhancement of the hadronic b quark decays
A. Czarnecki, M. Slusarczyk, F. V. Tkachov
A class of previously unknown strong-interaction corrections is found to enhance the rate of non-leptonic decays of the b quark by 5-8 percent. This effect decreases the predicted…
Next-to-next-to-leading order calculations for heavy-to-light decays
I. Blokland, A. Czarnecki, M. Slusarczyk +1
We present technical aspects of next-to-next-to-leading order calculations for heavy-to-light decays such as top quark decay, semileptonic b quark decay into a u quark, muon decay,…
Non-abelian color dielectric - towards the effective model of the low energy QCD
A. Wereszczynski, M. Slusarczyk
Lattice motivated triplet color scalar field theory is analyzed. We consider non-minimal as well as covariant derivative coupling with SU(2) gauge fields. Field configurations gene…
Two-loop QCD corrections to top quark decay
Maciej Slusarczyk
We present a determination of a new class of Feynman diagrams relevant for second-order QCD corrections to the top quark decay t -> b W. Modern computing techniques allow us to per…
Heavy-to-light decays with a two-loop accuracy
Ian Blokland, Andrzej Czarnecki, Maciej Slusarczyk +1
We present a determination of a new class of three-loop Feynman diagrams describing heavy-to-light transitions. We apply it to find the O(alpha_s^2) corrections to the top quark de…
