A Study of Hadron Deformation in Lattice QCD

Understand

We develop the formalism for the evaluation of density-density correlators in lattice QCD that includes techniques for the computation of the all-to-all propagators involved.

• A novel technique in this context is the implementation of the one-end trick in the meson sector.
• Density-density correlators provide a gauge invariant definition for the hadron wave function and yield information on hadron deformation.
• We evaluate density-density correlators using two degenerate flavors of dynamical Wilson fermions for the pion, the rho-meson, the nucleon and the $\Delta$.
