The Matter and the Pseudoscalar Densities in Lattice QCD

Abstract

The matter and the pseudoscalar densities inside a hadron are calculated via gauge-invariant equal-time correlation functions. A comparison is made between the charge charge and the matter density distributions for the pion, the rho, the nucleon and the $\hat{I}{”}^{+}$ within the quenched theory, and with two flavours of dynamical quarks.
