Hadron deformation from Lattice QCD
C. Alexandrou
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 γN Δ(1232) both in the quenched and in the unquenched theory.
