A Mixed Action Analysis of $\eta$ and ${\eta }^{\prime }$ Mesons

Konstantin Ottnad, Carsten Urbach, Falk Zimmermann

We study $\eta$ and ${\eta }^{\prime }$ 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 configuratio…
