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…

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…
