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
