The excited hadron spectrum in lattice QCD using a new method of estimating quark propagation
C. Morningstar, A. Bell, J. Bulava +7
Progress in determining the spectrum of excited baryons and mesons in lattice QCD is described. Large sets of carefully-designed hadron operators have been studied and their effect…
Excited-Nucleon Spectroscopy with 2+1 Fermion Flavors
Saul Cohen, John M. Bulava, Justin Foley +10
We present progress made by the Hadron Spectrum Collaboration (HSC) in determining the tower of excited nucleon states using 2+1-flavor anisotropic clover lattices. The HSC has bee…
First results from 2+1 dynamical quark flavors on an anisotropic lattice: light-hadron spectroscopy and setting the strange-quark mass
Huey-Wen Lin, Saul D. Cohen, Jozef Dudek +12
We present the first light-hadron spectroscopy on a set of dynamical, anisotropic lattices. A convenient set of coordinates that parameterize the two-dimensional plane of…
Group Theoretical Construction of Nucleon Operators using All-to-All Quark Propagators
R. G. Edwards, G. T. Fleming, B. Joo +5
We describe a method to construct irreducible baryon operators using all-to-all quark propagators. It was demonstrated earlier that a large basis of extended baryon operators on an…
Hadronic Resonances from Lattice QCD
John Bulava, Robert Edwards, George Fleming +6
The determination of the pattern of hadronic resonances as predicted by Quantum Chromodynamics requires the use of non-perturbative techniques. Lattice QCD has emerged as the domin…
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…
