Gauge invariance of form factors

Il Nuovo Cimento, 1961
Discussions on validity limits of quantum electrodynamics usually are based on a comparison of data with theory into which form factors are introduced. The assumption that nonlocal-theory defects do not affect conclusions drawn is not valid when the form factors destroy the gauge invariance of the theory. Methods avoiding this difficulty are presented.

Form factors and gauge invariance in pion photoproduction

Physical Review C, 1992
We consider the effect of strong-vertex form factors on the gauge invariance of Born diagrams for the pion photoproduction reaction. The minimal-substitution prescription of Ohta for the electromagnetic current operator in pion photoproduction yields the same result as the simplest Born approach for one particular invariant amplitude.
