A Mixed Action Analysis of $\eta$ and $\eta'$ Mesons
We study eta and eta' mesons and their mixing angle in a mixed action approach with so-called Osterwalder-Seiler valence quarks on a Wilson twisted mass sea. The gauge configurations have been generated by ETMC for 2+1+1 dynamical quark flavours and for three values of the lattice spacing. The...
