Gauge Invariant Smearing and Matrix Correlators using Wilson Fermions at beta=6.2

Abstract

We present an investigation of gauge invariant smearing for Wilson fermions on a $24^3\times 48$ lattice at $\beta =6.2$. 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.
