Abstract

A pedagogical overview of the formulation of the Fat-Link-Irrelevant-Clover (FLIC) fermion action and its associated phenomenology is described. The scaling analysis indicates FLIC fermions provide a new form of nonperturbative ℴ(a) improvement where near-continuum results are obtained at finite lattice spacing. Spin-(1/2) and spin-(3/2), even- and odd-parity baryon resonances are investigated in quenched QCD, where the nature of the Roper resonance and Λ*(1405) are of particular interest. FLIC fermions allow efficient access to the light-quark-mass regime, where evidence of chiral nonanalytic behavior in the Δ mass is observed.
