The negative-parity spin-1/2 $\Lambda$ baryon spectrum from lattice QCD and effective theory

Rafael Pavao, Philipp Gubler, Pedro Fernandez-Soler +3

The spectrum of the negative-parity spin-1/2 $\Lambda$ baryons is studied using lattice QCD and hadronic effective theory in a unitarized coupled-channel framework. A direct comparison b…
