MS4: a BPHZ killer
N. D. Lenshina, A. A. Radionov, F. V. Tkachov
The UV renormalization scheme emerged in the formalization of the reasoning which yielded an array of important algorithms in the 80's. guarantees finit…
A comment on the LLA method, the kT jet algorithm and the BFKL theory
F. V. Tkachov
The leading logarithmic approximation method fails to yield the correct asymptotic behavior in some realistic situations: inclusion of the beta-terms to which the LLA method is ins…
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,…
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…
A Monte Carlo Test of the Optimal Jet Definition
D. Yu. Grigoriev, E. Jankowski, F. V. Tkachov
We summarize the Optimal Jet Definition and present the result of a benchmark Monte Carlo test based on the W-boson mass extraction from fully hadronic decays of pairs of W's.
