WebGauge Invariance QCD Lagrangian is invariant under local gauge transformations. That is, one can redeﬁne quark ﬁelds independently at every point in space-time, qa(x) → q ′ a(x) = exp(it · θ(x))abqb(x) ≡ Ω(x)abqb(x) without changing physical content. Covariant derivative is so called because it transforms in same way as ﬁeld itself:

In gauge theory, which studies a particular class of fields which are of importance in quantum field theory, different fields are used in Lagrangians that are invariant under local gauge transformations.
