AB We examine analytically the ghost propagator Dyson-Schwinger Equation(DSE) in the deep IR regime and prove that a finite ghost dressing function at vanish-ing momentum is an alternative solution (solution II) to the usually assumed divergent one(solution I). We furthermore find that the Slavnov-Taylor identities discriminate betweenthese two classes of solutions and strongly support the solution II. The latter turns out tobe also preferred by lattice simulations within numerical uncertainties.
