Three-gluon vertex in arbitrary gauge and dimension
Three-gluon vertex in arbitrary gauge and dimension
One-loop off-shell contributions to the three-gluon vertex are calculated, in an arbitrary covariant gauge and in arbitrary space-time dimensions, including quark-loop contributions (with massless quarks). It is shown how one can get the results for all on-shell limits of interest directly from the general off-shell expression. The corresponding general expressions …
