Gauge-invariant two- and three- density correlators
C. Alexandrou, Ph. de Forcrand, A. Tsapalis
Abstract
Gauge-invariant spatial correlations between two and three quarks inside a hadron are measured within quenched and unquenched QCD. These correlators provide information on the shape and multipole moments of the pion, the rho, the nucleon and the Δ.
