A practical scheme for SU(4) flavour symmetry breaking in lattice gauge theories
Abstract
SU(4) flavour symmetry arises naturally in the continuum limit of free Susskind fermions on a four-dimensional lattice. It may be broken by including a mass term for each flavour. These is an optimum choice for the lattice mass term in the gauge theory, which breaks the flavour symmetry to SU(2) without increasing the non-locality of the action.
