nrqed said:By "renormalized" function, I meant the whole, final, renormalized amplitude, including the coupling constant. Clearly this cannot depend on the value of mu since mu is completely arbitrary.
A technical point: in general, an amplitude is not independent of [itex]\mu[/itex]; only infrared safe quantities are observable, and hence independent of [itex]\mu[/itex].
