C.7 Properties of flavor-singlet pseudo-scalar mesons from lattice QCD

C. Urbach

Properties of flavor singlet pseudo-scalar mesons will be computed in the non-perturbative framework of lattice QCD. The focus will be twofold: firstly, the determination of η and η' masses from the previous funding period will be improved systematically by reducing noise and by investigating the strange quark mass dependence. Secondly, a first computation of η-π scattering lengths will be performed.
