Abstract

We present new results for light quark masses. The calculations are performed using two flavours of O(a) improved Wilson fermions. We have reached lattice spacings as small as a 0.07fm and pion masses down to mπ 340MeV in our simulations. This gives us significantly better control on the chiral and continuum extrapolations.
