Pion-pion scattering and the timelike pion form factor from lattice QCD simulations using the stochastic LapH method
John Bulava, Ben Hörz, Brendan Fahy +3
We report on progress applying the stochastic LapH method to estimate all-to-all propagators required in correlation functions of multi-hadron operators relevant for pion-pion scat…
Excited-state energies and scattering phase shifts from lattice QCD with the stochastic LapH method
Colin Morningstar, John Bulava, Brendan Fahy +5
Recent results in computing excited-state energies and meson-meson scattering phase shifts in lattice QCD are presented. A stochastic method of treating the low-lying modes of quar…
B-meson spectroscopy in HQET at order 1/m
Fabio Bernardoni, Benoît Blossier, John Bulava +7
We present a study of the B spectrum performed in the framework of Heavy Quark Effective Theory expanded to next-to-leading order in 1/m and non-perturbative in the strong coupling…
Non-perturbative improvement and renormalization of the axial current in N_f=3 lattice QCD
John Bulava, Michele Della Morte, Jochen Heitger +1
We report on a non-perturbative computation of the renormalization factor Z_A of the axial vector current in three-flavour O(a) improved lattice QCD with Wilson quarks and tree-lev…
