2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/181624We 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 $m_π \sim 340$MeV in our simulations. This gives us significantly better control on the chiral and continuum extrapolations.6 pages, contribution to Lattice 2006High Energy Physics - Latticetext
