Abstract:	Our recent first-principles lattice-QCD exploration of the ground and first eleven excited states of the nucleon in the positive parity channel is presented. Of particular interest is the first positive-parity excitation of the uncleon; the Roper resonance. Using correlation-matrix methods developed by the CSSM Lattice Collaboration, a low-lying Roper state is observed in our full QCD analysis using the PACS-CS gauge fields made available via the ILDG. Our results for the Roper display significant curvature as the chiral regime is approached. © 2012 American Institute of Physics.
