The eta' meson at the physical point with Nf=2 Wilson twisted mass fermions


  • Prof. Carsten URBACH

Primary authors



We present results for the eta' meson and the topological susceptibility in Nf=2 flavour lattice QCD. The results are obtained using Wilson twisted mass fermions at maximal twist with pion masses ranging from 250 MeV down to the physical point. A comparison to literature values is performed giving a handle on discretisation effects. Eventually, the error scaling is investigated towards the physical point.
