| dc.description | In this work, we report the first lattice calculation of hyperon axial couplings, using the 2+1-flavor MILC configurations and domain-wall fermion valence quarks. Both the $Σ$ and $Ξ$ axial couplings are computed for the first time in lattice QCD. In particular we find that $g_{ΣΣ} = 0.450(21)_{\rm stat}(27)_{\rm syst}$ and $g_{ΞΞ} = -0.277(15)_{\rm stat}(19)_{\rm syst}$. | |
