Overlap quark propagator near the physical pion mass
Abstract
The Landau-gauge quark propagator is calculated using overlap fermions on 2+1-flavour dynamical fermion gauge fields from the PACS-CS collaboration with pion mass mπ 156 MeV and spatial volume (3 fm)3. The observed features of the mass and renormalisation functions are discussed, including a comparison with recent results using O(a)-improved Wilson fermions on 2-flavour dynamical gauge fields.
