Abstract: The quantum chromodynamics QCD sum rules for the Delta baryons are analyzedby taking into account the finite-width effects, through explicit utilizationof the Breit-Wigner shape. We apply a Monte-Carlo based analysis to the-traditional- and the parity-projected sum rules. The first Delta excitationstate is also considered as a sub-continuum resonance and the widths arecalculated using the mass values as input.
