Point transformations and renormalization in the unitary gauge: Renormalization effects. [Coupling constant, wave function, proper vertex]
We continue an analysis of two simple gauge theory models using point transformations rather than gauge transformations. The renormalization constants are examined directly in two gauges, the renormalization (Landau) and unitary gauges. Our result is that the individual coupling-constant renormalizations are identical when calculated in each of the above two gauges, although the wave-function and proper vertex renormalizations differ.
