Description
We will present the first ever determination of the nucleon spectrum using HISQ valence quarks in combination with the (2+1+1) MILC-HISQ sea quarks ensembles at the physical point. We performed analyses with both Bayesian and GEVP methods to demonstrate control over excited states, and three lattice spacings, $\sim$0.15fm, $\sim$0.12fm, and $\sim$0.09fm, were used to extrapolate to continuum. With the experience gained from the nucleon, we will also present preliminary results of $\Omega$ baryon spectrum on the same set of ensembles, explored as an alternative method of scale setting.
