Description
The study of strong scattering in Lattice QCD is enabled by the use of
the Luescher method, which defines a mapping between the two body
spectrum in the finite volume and the infinite volume scattering
amplitude. It however requires full and precise knowledge of the
spectrum in a given moving frame and irreducible representation. In this project we investigate the $\Delta$ (1232) resonance in the
pion-nucleon system. The focus of the talk is on the group theoretical
construction of single and multi hadron interpolating fields in various
moving frames and irreducible representations. We construct a varied
basis of interpolating fields in all of the relevant irreducible
representations and determine the relevant energy levels.
