Light baryon spectrum using improved interpolating operators
Lattice Hadron Physics Collaboration, S. Basak, R. G. Edwards +6
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 ope…
Lattice QCD determination of states with spin 5/2 or higher in the spectrum of nucleons
S. Basak, R. G. Edwards, G. T. Fleming +5
Energies for excited isospin 1/2 states that include the nucleon are computed using quenched, anisotropic lattices. Baryon interpolating field operators that are used include nonlo…
The Effect of Reduced Spatial Symmetries on Lattice States: Results for Non-zero Linear Momentum
David C. Moore, George T. Fleming
The irreducible representations of the cubic space group are described and used to determine the mapping of continuum states to lattice states with non-zero linear momentum. The Cl…
Multiparticle States and the Hadron Spectrum on the Lattice
David C. Moore, George T. Fleming
The Clebsch-Gordan decomposition is calculated for direct products of the irreducible representations of the cubic space group. These results are used to identify multiparticle sta…
Calculation of the nucleon axial charge in lattice QCD
D. B. Renner, R. G. Edwards, G. Fleming +6
Protons and neutrons have a rich structure in terms of their constituents, the quarks and gluons. Understanding this structure requires solving Quantum Chromodynamics (QCD). Howeve…
Baryon Operators and Baryon Spectroscopy
S. Basak, R. G. Edwards, G. T. Fleming +6
The issues involved in a determination of the baryon resonance spectrum in lattice QCD are discussed. The variational method is introduced and the need to construct a sufficient ba…
Towards a determination of the spectrum of QCD using a space-time lattice
K. J. Juge, A. Lichtl, C. Morningstar +6
Progress by the Lattice Hadron Physics Collaboration in determining the baryon and meson resonance spectrum of QCD using Monte Carlo methods with space-time lattices is described.…
