To calculate the topological susceptibility we use the field-theoretical method. As in the quenched case, a sharp drop is observed for the topological susceptibility across the phase transition.LATTICE98(confine)High Energy Physics - LatticeHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
