# ${\boldsymbol {\boldsymbol s}}$-QUARK MASS INSPIRE search

See the comment for the ${{\mathit u}}$ quark above.

We have normalized the $\overline{\rm{}MS}$ masses at a renormalization scale of $\mu$ = 2 GeV. Results quoted in the literature at $\mu$ = 1 GeV have been rescaled by dividing by $1.35$.

They also determine the quoted value ${{\overline{\mathit m}}_{{s}}}$(2 GeV) for ${{\mathit n}_{{f}}}$ = 4 dynamical flavors.
3  ANANTHANARAYAN 2016 determine ${{\overline{\mathit m}}_{{s}}}$(2 GeV) = $106.70$ $\pm9.36$ MeV and $74.47$ $\pm7.77$ MeV from fits to ALEPH and OPAL ${{\mathit \tau}}$ decay data, respectively. We have used the weighted average of the two.
4  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.
5  ARTHUR 2013 is a lattice computation using 2+1 dynamical domain wall fermions. Masses at ${{\mathit \mu}}$ = 3 GeV have been converted to ${{\mathit \mu}}$ = 2 GeV using conversion factors given in their paper.

8  DURR 2011 determine quark mass from a lattice computation of the meson spectrum using ${{\mathit N}_{{f}}}$ = 2 + 1 dynamical flavors. The lattice simulations were done at the physical quark mass, so that extrapolation in the quark mass was not needed.
9  CHAKRABORTY 2015 is a lattice QCD computation that determines ${\mathit m}_{{{\mathit c}}}$ and ${\mathit m}_{{{\mathit c}}}/{\mathit m}_{{{\mathit s}}}$ using pseudoscalar mesons masses tuned on gluon field configurations with 2+1+1 dynamical flavors of HISQ quarks with ${{\mathit u}}/{{\mathit d}}$ masses down to the physical value.

We have combined the systematic errors linearly.
