Decay constants and spectroscopy of mesons in lattice QCD using domain-wall fermions
B. Fahy, G. Cossu, S. Hashimoto +3
We report results of masses and decay constants of light and charmed pseudo-scalar mesons using lattice QCD with Möbius domain-wall fermions. Using this formulation we are able to…
Analysis of short-distance current correlators using OPE
M. Tomii, G. Cossu, B. Fahy +3
We investigate the correlators of flavor non-singlet bilinear operators calculated on the lattice at short distances. In the continuum theory, non-perturbative effects are encoded…
Charmonium current-current correlators with Mobius domain-wall fermion
Katsumasa Nakayama, Brendan Fahy, Shoji Hashimoto
We calculate the charmonium correlators on the lattice with Moebius domain wall fermion, and extract the charm quark mass and the strong coupling constant. Time moment…
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…
