and scattering phase shifts from lattice QCD
John Bulava, Brendan Fahy, Ben Hörz +3
The -wave and -wave elastic - scattering amplitudes are calculated from a first-principles lattice QCD simulation using a single ensemble of gauge field con…
Applications of the Stochastic LapH Method
John Bulava, Justin Foley, Keisuke J. Juge +5
Progress in computing the hadron spectrum in lattice QCD using stochastic LapH quark propaga- tors is described. The stochastic LapH algorithm is a particular quark smearing algori…
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…
Phase Shift with LapH Propagators
John Bulava, Justin Foley, Keisuke J. Juge +3
The pion-pion scattering phase shift is computed using LapH propagators. The LapH method for computing quark propagators is used to form two-particle correlation functions with a n…
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…
A novel quark-field creation operator construction for hadronic physics in lattice QCD
Michael Peardon, John Bulava, Justin Foley +7
A new quark-field smearing algorithm is defined which enables efficient calculations of a broad range of hadron correlation functions. The technique applies a low-rank operator to…
