3-GLUON VERTEX IN ARBITRARY GAUGE AND DIMENSION

One-loop off-shell contributions to the three-gluon vertex are calcula ted, in an arbitrary covariant gauge and in arbitrary space-time dimen sions, including quark-loop contributions (with massless quarks). It i s shown how one can get the results for all on-shell limits of interes t directly from the general off-shell expression. The corresponding ge neral expressions for the one-loop ghost-gluon vertex are also obtaine d. They allow for a check of consistency with the Ward-Slavnov-Taylor identity.
