QCD with Two Light Dynamical Chirally Improved Quarks: Baryons

Engel, Georg P., Lang, C. B., Mohler, Daniel et al.

Understand

We present a study of baryon ground states and low lying excitations of non-strange and strange baryons.

The results are based on seven gauge field ensembles with two dynamical light Chirally Improved (CI) quarks corresponding to pion masses between 255 and 596 MeV and a strange valence quark with mass fixed by the Omega baryon.
The lattice spacing varies between 0.1324 and 0.1398 fm.
Given in lattice units, the bulk of our results are for size 16^3\times 32, for two ensembles with light pion masses (255 and 330 MeV) we also use 24^3\times 48 lattices and perform an infinite volume extrapolation.
