Recent lattice results on the light quark masses

I discuss old and new determinations of the light quark masses using lattice QCD. Most lattice results using various approximations can be fit together in a simple picture which is consistent with lower values than conventionally supposed: in the quenched approximation for the strange quark mass in the MS scheme, ms(2 GeV)=95(16) MeV, and for the average of the u and d quark masses, ml(2 GeV)=3.6(6) MeV. An estimate of the effects of light quark loops yields answers lower still: ms(2 GeV) in the range 54-92 MeV, and ml(2 GeV) in the range 2.1-3.5 MeV. (orig.)
