We study the change of the QCD spectrum of low-lying mesons in the presenceof an external magnetic field using Wilson fermions in the quenchedapproximation. Motivated by qualitative differences observed in the spectra ofoverlap and Wilson fermions for large magnetic fields, we investigate thedependence of the additive quark mass renormalisation on the magnetic field. Weprovide evidence that the magnetic field changes the critical quark mass bothin the free case and on our quenched ensemble. The associated change of thebare quark mass with the magnetic field affects the spectrum and is relevantfor the magnetic field dependence of a number of related quantities. We deriveWard identities for lattice and continuum QCD+QED from which we can extract thecurrent quark masses. We also report on a first test of the tuning of the quarkmasses with the magnetic field using the current quark masses, and show thatthis tuning resolves the qualitative discrepancy between the Wilson and overlapspectra.
