Dynamical quark mass generation in a strong external magnetic field — •Niklas Mueller1,2, Christian S. Fischer1, and Jacqueline A. Bonnet1 — 1Justus-Liebig-Universität Giessen — 2Universität Heidelberg
We investigate the effect of a strong magnetic field on dynamical chiral symmetry breaking in quenched and unquenched QCD. To this end we apply the Ritus formalism to the coupled set of (truncated) Dyson-Schwinger equations for the quark and gluon propagator under the presence of an external constant Abelian magnetic field. We discuss the effect of the magnetic field onto the quark condensate and extract the chiral suszeptibility.
