Matching of \(N_f=2+1\) CLS ensembles to a tmQCD valence sector

A mixed action composed of valence quark flavours regularized with a fully-twisted tmQCD action and of \(N_f=2+1\) flavours of non-perturbatively \({\rm O}(a)\)-improved Wilson sea quarks is described. Two procedures for the matching of sea and valence quark masses are discussed. We report about a c...

Description
Summary:A mixed action composed of valence quark flavours regularized with a fully-twisted tmQCD action and of \(N_f=2+1\) flavours of non-perturbatively \({\rm O}(a)\)-improved Wilson sea quarks is described. Two procedures for the matching of sea and valence quark masses are discussed. We report about a comparison of the continuum-limit scaling of pseudoscalar meson observables and of quark masses using the sea and valence actions.
