1  CHAKRABORTY 2015 is a lattice QCD computation on gluon field configurations with 2+1+1 dynamical flavors of HISQ quarks with u/d masses down to the physical value. ${\mathit m}_{{{\mathit c}}}$ and ${\mathit m}_{{{\mathit s}}}$ are tuned from pseudoscalar meson masses.
2  BAZAVOV 2014A is a lattice computation using 4 dynamical flavors of HISQ fermions.
3  CARRASCO 2014 is a lattice QCD computation of light quark masses using 2 + 1 + 1 dynamical quarks, with ${{\mathit m}_{{u}}}$ = ${{\mathit m}_{{d}}}{}\not=$ ${{\mathit m}_{{s}}}{}\not=$ ${{\mathit m}_{{c}}}$. The ${\mathit {\mathit u}}$ and ${\mathit {\mathit d}}$ quark masses are obtained separately by using the ${{\mathit K}}$ meson mass splittings and lattice results for the electromagnetic contributions.
4  DURR 2012 determine ${\mathit m}_{{{\mathit c}}}/{\mathit m}_{{{\mathit s}}}$ using a lattice computation with ${{\mathit N}_{{f}}}$ = 2 dynamical fermions. The result is combined with other determinations of ${\mathit m}_{{{\mathit c}}}$ to obtain ${\mathit m}_{{{\mathit s}}}$(2 GeV) = $97.0$ $\pm2.6$ $\pm2.5~$MeV.
5  BLOSSIER 2010 determine ${\mathit m}_{{{\mathit c}}}/{\mathit m}_{{{\mathit s}}}$ from a computation of the hadron spectrum using ${{\mathit N}_{{f}}}$ = 2 dynamical twisted-mass Wilson fermions.
6  DAVIES 2010 determine ${\mathit m}_{{{\mathit c}}}/{\mathit m}_{{{\mathit s}}}$ from meson masses calculated on gluon fields including ${{\mathit u}}$, ${{\mathit d}}$, and ${{\mathit s}}$ sea quarks with lattice spacing down to 0.045 fm. The Highly Improved Staggered quark formalism is used for the valence quarks.
