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 $a \sim 0.07$ fm and pion masses down to $m_{\pi} \sim 340$ MeV in our simulations. This gives us significantly better control on the chiral and continuum extrapolations.
