Abstract

We present a lattice QCD determination of the average up-down, strange and charm quark masses based on simulations performed by the European Twisted Mass Collaboration with Nf=2+1+1 dynamical fermions. We simulated at three different values of the lattice spacing, the smallest being approximately 0.06fm, and with pion masses as small as 210MeV. Our results are: mud(2GeV)=3.70(17)MeV, ms(2GeV)=99.2(3.9)MeV, mc(mc)=1.350(49)GeV, ms/mud=26.64(30) and mc/ms=11.65(12).
