Abstract
In this work we study the effects of an external magnetic field in the competition of chiral and diquark order parameters in cold and dense quark matter, using a SU(2) version of the NJL model. We verify the influence of the magnetic field in the phase diagram, and perform a comparison of the results obtained using a Fermi-Dirac form factor regularization with ones obtained by using a method that makes a full separation of the finite magnetic contributions and the divergencies, the Magnetic Field Independent Regularization.
