Investigating a mixed action approach for η and η' mesons in Nf=2+1+1 lattice QCD
Konstantin Ottnad, Carsten Urbach, Falk Zimmermann
We present results for a test of a mixed action approach with Osterwalder-Seiler valence quarks on a Wilson twisted mass sea for the example η, η' mesons. Flavour singlet pseudosca…
η and η' masses and decay constants from lattice QCD with 2+1+1 quark flavours
Chris Michael, Konstantin Ottnad, Carsten Urbach
We investigate the masses and decay constants of eta and eta' mesons using the Wilson twisted mass formulation with N_f=2+1+1 dynamical quark flavours based on gauge configurations…
η and η' mixing from Lattice QCD
Chris Michael, Konstantin Ottnad, Carsten Urbach
We present a lattice QCD computation of and masses and mixing angles, for the first time controlling continuum and quark mass extrapolations. The results for the eta…
Determination of Low-Energy Constants of Wilson Chiral Perturbation Theory
Gregorio Herdoiza, Karl Jansen, Chris Michael +2
By matching Wilson twisted mass lattice QCD determinations of pseudoscalar meson masses to Wilson Chiral Perturbation Theory we determine the low-energy constants , an…
