Abstract
- We present the results of the nucleon and $\Omega$ baryon masses using staggered action for both valence and sea quarks. Three ensembles with the physical pion mass at approximate lattice spacings of $0.15$, $0.12$, and $0.088$fm are employed to extrapolate the masses to continuum and we obtain $M_N = 964(16)$ MeV and $M_\Omega = 1678(9)$. Both statistical and systematic uncertainties are included in the nucleon mass, whereas only the statistical uncertainty is accounted for in the $\Omega$ baryon mass.<br />Comment: 7 pages, 4 figures, proceedings of the 37th International Symposium on Lattice Field Theory, 16-22 June 2019, Wuhan, China
