WebJan 1, 2009 · We discussed a particularly important feature of QCD, namely the self-interaction of gluons. This self-interaction makes pure gluodynamics, i.e., QCD without quarks, an interesting, highly nontrivial theory. Pure gluodynamics shows color confinement, an important property of full QCD. WebQuantization of Gauge Fields We will now turn to the problem of the quantization of gauge th eories. We will begin with the simplest gauge theory, the free electromagnetic field. This is an abelian gauge theory. After that we will discuss at length the quantization of non-abelian gauge fields. Unlike abelian theories, such as the
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 Webgauge theories are not free fields and have highly non-trivialdynamics. 9.1 Canonical quantization of the free electromagnetic field The Maxwell theory was the first field …
