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…

A novel method for evaluating correlation functions in lattice hadron spectroscopy
Justin Foley, Chik Him Wong, John Bulava +4
We describe a new approach for evaluating hadronic correlation functions which combines Laplacian-Heaviside quark smearing with a stochastic estimator of quark propagators. This me…
