Lattice gauge theory is a method to deal with gauge theory that is useful for computer-assisted calculations. In lattice gauge theory, the spacetime is discretized and replaced by a lattice with lattice spacing equal to . The quark fields are only defined at the elements of the lattice and the gauge fields are defined on the links of the lattice. The Yang-Mills action is rewritten in such a way that the limit formally gives the original continuous action.

Lattice gauge theory is a particularly important tool for quantum chromodynamics (QCD). The discretized version of QCD is called Lattice QCD.

QCD scaleIn particle physics, QCD scale is the energy scale (or length scale) associated with the processes of Quantum chromodynamics (QCD), i. the processes involving quarks inside the proton, neutron, and other particles. It is roughly 150 MeV ( energy) or 10-15
