AB We present novel lattice results for the form factors of the quenched three-gluon vertex of QCD, intwo special kinematic configurations that depend on a single momentum scale. We consider three formfactors, two associated with a classical tensor structure and one without tree-level counterpart, exhibitingmarkedly different infrared behaviors. Specifically, while the former display the typical suppressiondriven by a negative logarithmic singularity at the origin, the latter saturates at a small negativeconstant. These exceptional features are analyzed within the Schwinger-Dyson framework, with the aidof special relations obtained from the Slavnov-Taylor identities of the theory. The emerging picture ofthe underlying dynamics is thoroughly corroborated by the lattice results, both qualitatively as well asquantitatively.
