Future work will include the extension of superconformal representations to pentaquark and other exotic hadrons, comparisons with lattice gauge theory predictions, the construction of an AdS/QCD orthonormal basis to diagonalize the QCD light-front Hamiltonian, hadronization at the amplitude level, and the computation of intrinsic heavy quark higher Fock states.
Last year, scientists associated with the LHCb experiment at the European Organization for Nuclear Research's Large Hadron Collider (LHC) (http://www.ibtimes.com/cerns-large-hadron-collider-discovers-elusive-pentaquark-2009319) announced the discovery of the pentaquark - an exotic new class of particles.

Over 150 papers highlight developments since the previous conference in 2002, among them the possible discovery of the pentaquark, developments in the four-body sector, new measurements showing interesting phenomena in baryon resonances, computational techniques and precision detectors revealing fine details of physics, and the ability to compare calculations based on effective field theory and experimental results.
Furthermore, we can apply this formalism straightforwardly for investigation of heavy pentaquark systems, which can be considered as two-body (heavy meson and baryon) systems with mesonnucleon potentials which is underway.
