| Abstract: | Results are reported for the first calculation of the low-lying spin-1/2 odd-parity octet baryon masses using O(a2) improved gluon and fermion actions. Methods for removing even-parity ground-state contaminations from the two-point correlation functions at zero and finite momenta are outlined. We investigate the properties of two odd-parity interpolating fields based on the established interpolating fields for the nucleon ground state. Isolation of the lowest-lying odd-parity state appears to be sufficient to begin exploring odd-parity N → N* electromagnetic transition form factors. |
