Mesons in non-local chiral quark models
arXiv:hep-ph/9911204 · doi:10.1063/1.1303044
Abstract
Vector meson correlators are studied in effective chiral quark models with both local and non-local regulators. A set of sum rules based on dispersion relations is derived, which allows for a comparison of model predictions to data. We show that the two Weinberg sum rules for vector correlators hold in the non-local model.
