  N* masses in the spin-1/2 and spin-3/2 sectors are computed using two
non-perturbative methods: lattice QCD and QCD sum rules. States with both
positive and negative parity are isolated via parity projection methods. The
basic pattern of the mass splittings is consistent with experiments. The mass
splitting within the same parity pair is directly linked to the chiral symmetry
breaking QCD.
