Both regular (the zero-momentum ghost dressing function not diverging), alsonamed decoupling, and critical (diverging), also named scaling, Yang-Millspropagators solutions can be obtained by analyzing the low-momentum behaviourof the ghost propagator Dyson-Schwinger equation (DSE) in Landau gauge. Theasymptotic expression obtained for the regular or decoupling ghost dressingfunction up to the order ${\cal O}(q^2)$ fits pretty well the low-momentumghost propagator obtained through the numerical integration of the coupledgluon and ghost DSE in the PT-BFM scheme. Furthermore, when the size of thecoupling renormalized at some scale approaches some critical value, the PT-BFMresults seems to tend to the the scaling solution as a limiting case.
