Description

We present results of the first fully-dynamical lattice QCD determination of hyperon-nucleon scattering. One s-wave phase shift was determined for nΛ scattering in both spin-channels at pion masses of 350, 490 and 590 MeV, and for nΣ- 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∼0.125fm
