Query: The renormalised quark mass in the Schrodinger functional of lattice QCD
  - a one-loop calculation with a non-vanishing background field   The critical quark mass, at which the renormalised mass vanishes, is computed
in the Schrodinger functional scheme with a non vanishing background field at
one-loop order of perturbation theory. Further one-loop calculations are done
for the renormalisation constant of the pseudo scalar density and for several
discretisation errors and compared to results obtained with a vanishing
background field.
