η,η′ mesons in 2+1+1 twisted mass lattice QCDKonstantin Ottnad1,2, Carsten Urbach1,2, and •Falk Zimmermann1,21Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn — 2European Twisted Mass Collaboration

The twisted mass formulation of lattice QCD is a framework for simulations with an even number of dynamical quarks which benefits from automatic O(a) improvement.

Analysing suitable correlation functions, we focus on the mass splitting between the η and η′ meson and related quantities in a setup with 2+1+1 dynamical quarks. In addition to the unitary setup, a different regularization of valence and sea quarks (Osterwalder-Seiler approach) is employed to study the strange quark mass dependence.
