Lattice baryons in the 1/N expansion
arXiv:1205.0235 · doi:10.1103/PhysRevD.86.034508
Abstract
Results are presented for hadron spectroscopy with gauge groups SU(N) with N=3, 5, 7. Calculations use the quenched approximation. Lattice spacings are matched using the static potential. Meson spectra show independence on N and vacuum-to-hadron matrix elements scale as the square root of N. The baryon spectrum shows the excitation levels of a rigid rotor.
