Finite-width effects on Delta baryons in QCD Sum Rules
Jan, 2008Citations per year
Abstract: (Elsevier)
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.- 14.20.Gk
