Improving the Excited Nucleon Spectrum in Hard-Wall AdS/QCD
arXiv:1002.4352 · doi:10.1103/PhysRevD.81.114029
Abstract
We show that the nucleon spectrum in a hard-wall AdS/QCD model can be improved by use of a relatively large IR cutoff. All of the spin-1/2 nucleon masses listed in PDG can be fit quite well within 11%. The average error is remarkably only 4.66%.
