We present a report on progress about our project aimed at determining the behavior of the anomaly term around the chiral phase transition for two light flavors, which is known to be strictly related to the order of the phase transition itself. In particular we discuss our method for determining the eta prime mass by measuring topological charge correlators and present preliminary results.
