Hadron deformation from Lattice QCD

Abstract

We address the issue of hadron deformation within the framework of lattice QCD. For hadrons with spin greater than 1/2 the deformation can be determined by evaluating the charge and matter distributions. Deviation of the nucleon shape from spherical symmetry is determined by evaluating the quadrupole strength in the transition $\gamma N\to \Delta (1232)$ both in the quenched and in the unquenched theory.
