  The temperature dependence of the Landau gauge ghost propagator is
investigated in pure SU(3) Yang-Mills theory with lattice QCD simulations. Its
behavior around the confined-deconfined phase transition temperature, $T_c \sim
270$ MeV, is investigated. The simulations show that in the deconfined phase,
the ghost propagator is enhanced for small momenta, $\lesssim 1$ GeV.
Furthermore, the analysis of the spontaneous breaking of center symmetry on the
ghost propagator is studied. Similarly as observed for the gluon propagator,
the simulations result in a decoupling of the sectors where the phase of the
Polyakov loop is either 0 or $\pm 2\pi/3$ sectors, with the latter remaining
indistinguishable. The results point to the possible use of the ghost
propagator as an "order parameter" for the confined-deconfined phase
transition.
