Abstract

Quark correlation functions and Bethe-Salpeter wave functions for the pion, rho, and nucleon are calculated in quenched lattice QCD and compared with the MIT bag and Skyrme models. Correction for finite lattice image effects allows reconstruction of density-density correlation functions out to the asymptotic region of exponential decay, and the use of extended bag model sources greatly improves the overlap with physical hadrons.
