摘要：The effects of Gaussian quark-field smearing and analytic stout-link smearing on the correlations
of gauge-invariant extended baryon operators are studied. Gaussian quark-field smearing substantially
reduces contributions from the short wavelength modes of the theory, while stout-link
smearing significantly reduces the noise from the stochastic evaluations. The use of gauge-link
smearing is shown to be crucial for baryon operators constructed of covariantly-displaced quark
fields. Preferred smearing parameters are determined for a lattice spacing as 0:1 fm.
