Hyperon-Nucleon Scattering from Fully-Dynamical Lattice QCD
Silas R. Beane, Paulo F. Bedaque, Thomas C. Luu +4
We present results of the first fully-dynamical lattice QCD determination of hyperon-nucleon scattering. One s-wave phase shift was determined for n Lambda scattering in both spin-…
Pi-K Scattering in Full QCD with Domain-Wall Valence Quarks
Silas R. Beane, Paulo F. Bedaque, Thomas C. Luu +4
We calculate the pi+ K+ scattering length in fully-dynamical lattice QCD with domain-wall valence quarks on MILC lattices with rooted staggered sea-quarks at a lattice spacing of b…
f_K/f_pi in Full QCD with Domain Wall Valence Quarks
S. R. Beane, P. F. Bedaque, K. Orginos +1
We compute the ratio of pseudoscalar decay constants f_K/f_pi using domain-wall valence quarks and rooted improved Kogut-Susskind sea quarks. By employing continuum chiral perturba…
Strong-Isospin Violation in the Neutron-Proton Mass Difference from Fully-Dynamical Lattice QCD and PQQCD
Silas R. Beane, Kostas Orginos, Martin J. Savage
We determine the strong-isospin violating component of the neutron-proton mass difference from fully-dynamical lattice QCD and partially-quenched QCD calculations of the nucleon ma…
The Gell-Mann -- Okubo mass relation among baryons from fully-dynamical mixed-action lattice QCD
Silas R. Beane, Kostas Orginos, Martin J. Savage
We explore the Gell-Mann--Okubo mass relation among the octet baryons using fully-dynamical, mixed-action (domain-wall on rooted-staggered) lattice QCD calculations at a lattice sp…
