In the field of quantum chromodynamics, what is known as Symanzik’s effective field theory (Symanzik 82, Symanzik 83) is a type of effective field theory used in lattice QCD in order to deal with lattice-spacing effects.
In lattice QCD, the extraction of hadronic observables involves setting a scale for a particular lattice action functional with given sea-quark configurations. This involves the extrapolation of the dimensionless product of various quantities, such as gradient-flow scales and the omega baryon mass, to the continuum and infinite volume limit. This is in turn, interpolated to quark mass points in the isospin limit. These extrapolation functions must incorporate:
Light and Strange Quark Mass Dependence
Finite Volume Corrections
Discretization Corrections
Symanzik’s effective field theory is constructed by expanding the discretized action about the continuum limit.
