Anomaly physics - Examples

In physics, an anomaly is a classical symmetry — a symmetry of the Lagrangian — that is broken in quantum field theories. Any anomaly can be considered to be a short-distance effect (an ultraviolet effect, in the language of quantum field theory), since it arises during the process of renormalization, when some divergent integrals cannot be regularized in such a way that all the symmetries are preserved simultaneously. However, their effects are often felt at long distances (i.e., by the infra-red physics, in the language o ...
