Query: Light baryon spectrum using improved interpolating operators   Energies for excited light baryons are computed in quenched QCD with a pion
mass of 490 MeV. Operators used in the simulations include local operators and
the simplest nonlocal operators that have nontrivial orbital structures. All
operators are designed with the use of Clebsch-Gordan coefficients of the
octahedral group so that they transform irreducibly under the group rotations.
Matrices of correlation functions are computed for each irreducible
representation, and then the variational method is applied to separate mass
eigenstates. We obtained 17 states for isospin 1/2 and 11 states for isospin
3/2 in various spin-parity channels including $J^P=5/2^\pm$. The pattern of the
lowest-lying energies from each irrep is discussed. We use anisotropic lattices
of volume $24^3\times 64$ with temporal lattice spacing $a_t^{-1}=6.05$ GeV
with renormalized anisotropy $\xi=3.0$.
