Abstract
We present an investigation of gauge-invariant smearing for Wilson fermions in quenched lattice QCD on a ×48 lattice at . We demonstrate a smearing algorithm that allows a substantial improvement in the determination of the baryon spectrum obtained using propagators smeared at both source and sink, at only a small computational cost. We investigate the matrix of correlators constructed from local and smeared operators, and are able to expose excited states of both the mesons and baryons.
