WebAnswer (1 of 3): QCD is much, much harder. In fact, knowing QED is pretty much a prerequisite for knowing QCD. As for why, let me first preface this by saying that I am comfortable with solving most “entry-level” QED problems (electron anomalous magnetic moment, tree-level and one-loop level diag... WebMay 10, 2024 · We identify infinitely many non-invertible generalized global symmetries in QED and QCD for the real world in the massless limit. In QED, while there is no conserved Noether current for the axial symmetry because of the ABJ anomaly, for every rational angle , we construct a conserved and gauge-invariant topological symmetry operator.

WebBut that's possible in QED. But that will not be possible in QCD, because at momentum transfer 0, the coupling is going to be infinite.
