Light quark masses in $${N_\mathrm{f}=2+1}$$ lattice QCD with Wilson fermions
Light quark masses in $${N_\mathrm{f}=2+1}$$ lattice QCD with Wilson fermions
We present a lattice QCD determination of light quark masses with three sea-quark flavours ($N_f = 2+1$). Bare quark masses are known from PCAC relations in the framework of CLS lattice computations with a non-perturbatively improved Wilson-Clover action and a tree-level Symanzik improved gauge action. They are fully non-perturbatively improved, …
