Remarks on the discretization of physical momenta in lattice QCD

摘要

relevant physical processes is complicated by the spatial momenta\ud quantization rule arising from the introduction of limited box sizes in\ud numerical simulations. A method to overcome this problem, based on the\ud adoption of two distinct boundary conditions for two fermions species on\ud a finite lattice, is here discussed and numerical results supporting the\ud physical significance of this procedure are shown.
