Phase diagram of strong interactions in an external magnetic field

The structure of the phase diagram for strong interactions becomes richer in the presence of a magnetic back- ground, which enters as a new control parameter for the thermodynamics. Motivated by the relevance of this physical setting for current and future high energy heavy ion collision experiments and for the cosmological QCD transitions, we use the linear sigma model coupled to quarks and to Polyakov loops as an effective theory to investigate how the chiral and the deconfining transitions are affected, and present a general picture for the temperature magnetic field phase diagram.
