چکیده
|
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 p 0 → gg decay is perhaps the most notable impossible effect allowed by anomalies.
