We discuss the chiral properties of Nf = 2 QCD in presence of a strong magnetic field, as they emerge from lattice numerical simulations in the low temperature regime. We focus on magnetic catalysis, i.e. the increase of chiral symmetry breaking induced by the background field. We show that a substantial contribution to magnetic catalysis comes from the modified distribution of non-Abelian gauge fields, induced by the magnetic field via dynamical quark loop effects.

Abstract
We discuss the chiral properties of Nf = 2 QCD in presence of a strong magnetic field, as they emerge from lattice numerical simulations in the low temperature regime. We focus on magnetic catalysis, i.e. the increase of chiral symmetry breaking induced by the background field. We show that a substantial contribution to magnetic catalysis comes from the modified distribution of non-Abelian gauge fields, induced by the magnetic field via dynamical quark loop effects.File in questo prodotto:
