    N* masses from an anisotropic lattice QCD action
    (Elsevier Science BV, 2002) Lee, F.; Leinweber, D.; Zhou, L.; Zanotti, J.; Choe, S.; 19th International Symposium on Lattice Field Theory (19 Aug 2001 - 24 Aug 2001 : BERLIN, GERMANY); Centre for the Sub-Atomic Structure of Matter (CSSM)
    We report N* masses in the spin-3/2 sector from a highly-improved anisotropic action. States with both positive and negative parity are isolated via a parity projection method. The extent to which spin projection is needed is examined. The gross features of the splittings from the nucleon ground state show a trend consistent with experimental results at the quark masses explored.
