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 and the matter density distributions for the pion, the rho, the nucleon and the Δ+ within the quenched theory, and with two flavors of dynamical quarks. © 2003 The American Physical Society.
