Query: Excited Baryons from the FLIC Fermion Action   Masses of positive and negative parity excited nucleons and hyperons are
calculated in quenched lattice QCD using an O(a^2) improved gluon action and a
fat-link clover fermion action in which only the irrelevant operators are
constructed with fat links. The results are in agreement with earlier N*
simulations with improved actions, and exhibit a clear mass splitting between
the nucleon and its parity partner, as well as a small mass splitting between
the two low-lying J^P={1/2}^- N* states. Study of different Lambda
interpolating fields suggests a similar splitting between the lowest two
{1/2}^- Lambda* states, although the empirical mass suppression of the
Lambda*(1405) is not seen.
