Finite-width effects on Delta baryons in QCD Sum Rules
arXiv:0801.0783 · doi:10.1016/j.nuclphysa.2008.01.001
Abstract
The quantum chromodynamics (QCD) sum rules for the Delta baryons are analyzed by taking into account the finite-width effects, through explicit utilization of the Breit-Wigner shape. We apply a Monte-Carlo based analysis to the 'traditional' and the parity-projected sum rules. The first Delta excitation state is also considered as a sub-continuum resonance and the widths are calculated using the mass values as input.
