On cutoff effects in lattice QCD from short to long distances
Michele Della Morte, Rainer Sommer, Shinji Takeda
We discuss kinematical enhancements of cutoff effects at short and intermediate distances. Starting from a pedagogical example with periodic boundary conditions, we switch to the c…

Towards a non-perturbative matching of HQET and QCD with dynamical light quarks
Michele Della Morte, Patrick Fritzsch, Jochen Heitger +3
We explain how the strategy of solving renormalization problems in HQET non-perturbatively by a matching to QCD in finite volume can be implemented to include dynamical fermions. A…
