Pole versus Breit-Wigner resonance description of the orbitally excited baryons
- Department of Physics, Virginia Tech, Blacksburg, Virginia 24061 (United States)
We consider the masses used in recent studies involving the nonstrange sector of the l=1 baryons. The use of {ital T}-matrix and {ital K}-matrix poles versus the conventional Breit-Wigner masses is discussed within the context of a large-N{sub c} fitting scheme. {copyright} {ital 1999} {ital The American Physical Society}
