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…
A novel algorithm for computing quark propagators for lattice hadron spectroscopy
J. Bulava, J. Foley, Y. C. Jhang +5
We report on our progress in computing the excitation spectrum in Lattice QCD. We focus on the isospin 0, 1 and 2 channels using the stochastic LapH algorithm for the quark propaga…
Extended hadron and two-hadron operators of definite momentum for spectrum calculations in lattice QCD
C. Morningstar, J. Bulava, B. Fahy +5
Multi-hadron operators are crucial for reliably extracting the masses of excited states lying above multi-hadron thresholds in lattice QCD Monte Carlo calculations. The constructio…
The excited hadron spectrum in lattice QCD using a new variance reduction method
Colin Morningstar, A. Bell, C. Y. Chen +6
Progress in calculating the spectrum of excited baryons and mesons in lattice QCD is described. Correlation matrices of sets of spatially-extended hadron operators have been studie…
