Pion Nucleon Scattering: Some Results from Lattice QCD

Understand

Including the meson-baryon (5 quark) intermediate states in a lattice simulation is challenging.

• However, it is important in order to obtain the correct energy eigenstates and to relate them to scattering phase shifts.
• Recent results for the negative parity nucleon channel and the problem of baryonic resonances in lattice calculations are discussed.
