B meson spectrum and decay constant from Nf=2 simulations
Benoit Blossier, John Bulava, Michele Della Morte +8
We report on the status of an ALPHA Collaboration project to extract quantities for B physics phenomenology from Nf=2 lattice simulations. The framework is Heavy Quark Effective Th…
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…
The B*Bpi Coupling in the Static Limit
J. Bulava, M. A. Donnellan, Rainer Sommer
We study an accurate method for the lattice calculation of the B*Bpi Coupling in the static limit, paying particular attention to excited state contamination. As this coupling is a…
Nucleon, Delta and Omega excited state spectra at three pion mass values
John Bulava, Robert G. Edwards, Bálint Joó +5
The energies of the excited states of the Nucleon, Delta and Omega are computed in lattice QCD, using two light quarks and one strange quark on anisotropic lattices. The calculatio…
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…
