Lattice gauge theory Guide, Meaning , Facts, Information and Description
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.
