abstract = {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 between
these two classes of solutions and strongly support the solution II. The latter turns out to
be also preferred by lattice simulations within numerical uncertainties.},
