We also determine $m_{\\Xi^-} - m_{\\Xi^0}|_{QCD} = 5.44\\pm0.31$ MeV. The calculation is performed at three values of the pion mass, with several values of the quark mass splitting and multiple lattice volumes, but only a single lattice spacing and an estimate of discretization errors. The calculations are performed on the anisotropic clover-Wilson ensembles generated by the Hadron Spectrum Collaboration. The omega-baryon ma","authors_text":"Andre Walker-Loud, Balint Joo, Brian C.
