The role of the pion mass on the QCD phase diagram in the $T-eB$ plane

Abstract

We investigated the role of the pion mass on the QCD phase diagram in the $T-eB$ plane using an effective model treatment. Such treatments are able to capture the main features predicted by first-principles calculations. We also employed the model to estimate the pion mass beyond which the inverse magnetic catalysis (IMC) effect disappears. The value is found to be independent of the strength of the magnetic field.
