Quark mass dependence of the pseudoscalar hairpin vertex
W. Bardeen, E. Eichten, H. Thacker
In a recent investigation of chiral behavior in quenched lattice QCD, the flavor-singlet pseudoscalar ``hairpin'' vertex associated with the eta prime mass was studied for pion mas…

Computing Electromagnetic Effects in Fully Unquenched QCD
A. Duncan, E. Eichten, R. Sedgewick
The inclusion of electromagnetic effects in unquenched QCD can be accomplished using ensembles generated in dynamical simulations with pure QCD provided the change in the quark det…

Chiral Lagrangian Parameters for Scalar and Pseudoscalar Mesons
W. Bardeen, E. Eichten, H. Thacker
The results of a high-statistics study of scalar and pseudoscalar meson propagators in quenched lattice QCD are presented. For two values of lattice spacing, ($a \approx .1…
