Hadronic Correlators from All-point Quark Propagators
arXiv:hep-lat/0110141 · doi:10.1016/S0920-5632(01)01928-4
Abstract
A method for computing all-point quark propagators is applied to a variety of processes of physical interest in lattice QCD. The method allows, for example, efficient calculation of disconnected parts and full momentum-space 2 and 3 point functions. Examples discussed include: extraction of chiral Lagrangian parameters from current correlators, the pion form factor, and the unquenched eta-prime.
