Simulating at Realistic Quark Masses: Light quark masses

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.
