Effects of Quark Interactions on Dynamical Chiral Symmetry Breaking by a Magnetic Field

Abstract

It is shown how the strong interaction dynamics of a multi-quark Lagrangian affects the catalysis of dynamical symmetry breaking by a constant magnetic field in (3+1) dimensions. Attention is drawn to the local minima structure of the theory.
