WebIn physics, a gauge theory is a type of field theory in which the Lagrangian (and hence the dynamics of the system itself) does not change (is invariant) under local transformations … Webwhich is just a gauge transformation of a vector potential Aµ. In other words, if one couples a globally U(1) symmetric theory to a gauge ﬁeld Aµ by the covariant derivative ∂µ → Dµ ≡ ∂µ + iQAµ, one ends up with a locally symmetric U(1) theory. This way of coupling a gauge potential to a matter ﬁeld is traditionally called grant thornton iselin
