The sea quark masses are at present in the range <F>SHAPE="CASE" ALIGN="C" STYLE="S"><NU>1</NU><DE>3</DE></FR>ms ≤ mud ≤ SHAPE="CASE" ALIGN="C" STYLE="S"><NU>2</NU><DE>3</DE></FR>ms</F> whereas the valence quark masses satisfy <F>SHAPE="CASE" ALIGN="C" STYLE="S"><NU>1</NU><DE>2</DE></FR>msea ≤ mval ≤ 2msea</F>. The values of the Gasser-Leutwyler low energy constants <F>L4, L5, L6</F> and <F>L8</F> are estimated. The computation is done with the Wilson-quark lattice action at gauge coupling β = 5.1 on 164 lattices. O(a) effects are taken into account by applying chiral perturbation theory for the Wilson lattice action as proposed by Rupak and Shoresh.
