  QCD sum rules for decuplet baryon two-point functions are investigated using
a comprehensive Monte-Carlo based procedure. In this procedure, all
uncertainties in the QCD input parameters are incorporated simultaneously,
resulting in realistic estimates of the uncertainties in the extracted
phenomenological parameters. Correlations between the QCD input parameters and
the phenomenological parameters are studied by way of scatter plots. The
predicted couplings are useful in evaluating matrix elements of decuplet
baryons in the QCD sum rule approach. They are also used to check a cubic
scaling law between baryon couplings and masses, as recently found by Dey and
coworkers. The results show a significant reduction in the scaling constant and
some possible deviations from the cubic law.
