We study the phase diagram in the T-mu plane for quarkmatter under the influence of a strong uniform magnetic field B, 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-mu 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.
