Abstract
We present results for the light quark masses obtained from a lattice QCD simulation with Nf=2 degenerate Wilson dynamical quark flavours. The sea quark masses of our lattice, of spacing aâ0.06fm, are relatively heavy, i.e., they cover the range corresponding to 0.60â²MP/MVâ²0.75. After implementing the non-perturbative RI-MOM method to renormalise quark masses, we obtain mudMS¯(2GeV)=4.3±0.4â0+1.1MeV, and msMS¯(2GeV)=101±8â0+25MeV, which are about 15% larger than they would be if renormalised perturbatively. In addition, we show that the above results are compatible with those obtained in a quenched simulation with a similar lattice.
