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…
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…
Optimal Jet Finder
D. Yu. Grigoriev, E. Jankowski, F. V. Tkachov
We describe a FORTRAN 77 implementation of the optimal jet definition for identification of jets in hadronic final states of particle collisions. We discuss details of the implemen…
Towards a standard jet definition
D. Yu. Grigoriev, E. Jankowski, F. V. Tkachov
In a simulated measurement of the -boson mass, evaluation of Fisher's information shows the optimal jet definition to be physically equivalent to the algorithm wh…
Quasi-optimal observables vs. event selection cuts
Fyodor V. Tkachov
The method of quasi-optimal observables [hep-ph/0001019] offers a fundamental yet simple and flexible algorithmic framework for data processing in high energy physics to improve up…
From novel mathematics to efficient algorithms. Do we have proper SD foundation to build future?
F. V. Tkachov
Computer implementation of sophisticated algorithms for physics applications is greatly facilitated by the new generation of component-oriented SD technologies pioneered by Wirth's…
