Hyperon-nucleon scattering from fully-dynamical lattice QCD
Abstract
We present results of the first fully-dynamical lattice QCD determination of hyperon-nucleon scattering. One s-wave phase shift was determined for it A scattering in both spin-channels at pion masses of 350, 490 and 590 MeV, and for n Sigma(-) scattering in both spin channels at pion masses of 490 and 590 MeV. The calculations were performed with domain-wall valence quarks on dynamical, staggered gauge configurations with a lattice spacing of b similar to 0.125 fm. (C) 2007 Elsevier B.V.
