AB We explore whether a tree-level expression for the gluon two-point function, supposed to express effectsof an horizon term introduced to eliminate the Gribov ambiguity, is consistent with the propagator obtainedin simulations of lattice-regularized quantum chromodynamics (QCD). In doing so, we insist that the gluontwo-point function obey constraints that ensure a minimal level of consistency with parton-like behavior onthe ultraviolet domain. In consequence, we are led to a position which supports a conjecture that the gluonmass and horizon scale are equivalent emergent mass-scales, each with a value of roughly 0.5 GeV; andwherefrom it appears plausible that the dynamical generation of a running gluon mass may alone besufficient to remove the Gribov ambiguity.
