Query: Light quark masses for dynamical, non-perturbatively O(a) improved
  Wilson fermions   We present results for the light quark masses in lattice QCD with two
degenerate flavours of dynamical fermions. We used configurations generated by
the UKQCD and QCDSF collaborations at six different combinations of beta and
kappa_sea.
