| description | Introduction/purpose: Noether’s theorem connects symmetry of the Lagrangian to conserved quantities. Quantum effects cancel the conserved
quantities.
Methods: Triangle diagram, Path integral, Pauli-Villars regularisation.
Results: Quantum effects that spoil conserved quantities of local gauge
symmetries endager renormalisability.
Conclusion: A careful treatment of anomalies is needed in order to obtain correct results. The π0 → γγ decay is perhaps the most notable
“impossible” effect allowed by anomalies. |
