Construction of gauge invariant effective nucleonic theories: functional approach
H. W. L. Naus
Starting from relativistic quantum field theories, describing interacting nucleons and pions coupled to the dynamical electromagnetic field, the pion degrees of freedom are elimina…

Local gauge invariance implies Siegert's hypothesis
H. W. L. Naus
The nonrelativistic Ward-Takahashi identity, a consequence of local gauge invariance in quantum mechanics, shows the necessity of exchange current contributions in case of nonlocal…

Analysis of the Low-Energy Theorem for γp \to p π^0
H. W. L. Naus, R. M. Davidson
The derivation of the `classical' low-energy theorem (LET) for γp \rightarrow pπ^0 is re-examined and compared to chiral perturbation theory. Both results are correct and are not c…
