2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/222027We discuss kinematical enhancements of cutoff effects at short and intermediate distances. Starting from a pedagogical example with periodic boundary conditions, we switch to the case of the Schroedinger Functional, where the theoretical analysis is checked by precise numerical data with Nf=2 dynamical O(a)-improved Wilson quarks. Finally we present an improved determination of the renormalization of the axial current in that theory.16 pages, 4 figures and 2 tables. References modifiedHigh Energy Physics - Latticetext
