Consider, for example, the gluon propagator $$D^{\mu\nu}(q)=-\frac{i}{q^2+i\epsilon}[D(q^2)T^{\mu\nu}_q+\xi L^{\mu\nu}_q]$$
What exactly is the renormalized gluon dressing function ##D(q^2)## and what is its definition? My interest is in knowing if I can then write the bare version of this function simply as ##D_B(q^2)=Z_AD(q^2)##, where ##Z_A## is the renormalization constant for the gluon field (##A_B=Z_A^{\frac{1}{2}}A##).
