Negative-parity Nucleon Resonance in the QCD Sum Rule
arXiv:hep-ph/9604280 · doi:10.1103/PhysRevD.54.4532
Abstract
The negative-parity baryons are studied by a novel approach in the QCD sum rule. It is found that the parity of the ground-state nucleon is determined by the sign of the quark condensate. We predict the mass of negative-parity nucleon.
