STRANGE BARYON PHYSICS
IN FULL LATTICE QCD

 ABSTRACT

Strange baryon spectra and form factors are key probes to study excited nuclear matter. The use of lattice QCD allows us to test the strength of the Standard Model by calculating strange baryon quantities from first principles. In this talk, I will discuss recent calculations from 2+1-flavor lattice ensembles, first focusing on baryon spectroscopy, including excited parity partners. I will also report on recent progress determining the Sigma and Cascade axial- charge couplings, form factors and semileptonic decays.

Everyone is welcome
