The epsilon regime with Wilson fermions
Oliver Bar, Silvia Necco, Stefan Schaefer
We study the impact of explicit chiral symmetry breaking of Wilson fermions on mesonic correlators in the epsilon-regime using Wilson chiral perturbation theory (WChPT). We general…
Epsilon regime calculations with reweighted clover fermions
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
We perform fully dynamical simulations at small quark masses by reweighting in the quark mass, calculating the weight factors stochastically. This approach avoids some of the techn…
physics from fine lattices
Georg von Hippel, Rainer Sommer, Jochen Heitger +2
We present a preliminary analysis of the charm quark mass and the mass and decay constant of the meson obtained from dynamical simulations of Wilson QCD o…
Low energy chiral constants from epsilon-regime simulations with improved Wilson fermions
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
We present a lattice QCD calculation of the low energy constants of the leading order chiral Lagrangian. In these simulations the epsilon regime is reached by using tree-level impr…
Reweighting towards the chiral limit
Anna Hasenfratz, Roland Hoffmann, Stefan Schaefer
We propose to perform fully dynamical simulations at small quark masses by reweighting in the quark mass. This approach avoids some of the technical difficulties associated with di…
