Abstract

AbstractWe study the phase diagram in the T − μ plane for quark matter under the influence of a strong uniform magnetic field , in the framework of a non‐local extension of the two‐flavor Polyakov–Nambu–Jona‐Lasinio model. We analyze the deconfinement and chiral symmetry restoration transitions in the mean field approximation. For the considered parameterization, it is found that there is always a critical end point (CEP) in the T − μ plane that separates a first‐order transition line from a smooth crossover. The location of the CEP is studied as a function of the magnetic field.
