Description
Recent progress in studying baryon resonances using lattice QCD is presented. Systems involving meson-baryon scattering, such as the Lambda(1405) resonance, and baryon-baryon scattering are discussed. Discrepancies between various lattice QCD determinations of nucleon-nucleon scattering phase shifts are outlined and an explanation is proffered. An outlook for treating systems such as the Roper resonance is given.
