Query: The negative-parity spin-1/2 $\Lambda$ baryon spectrum from lattice QCD
  and effective theory   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 between the two approaches is possible by
considering the hadronic effective theory in a finite volume and with hadron
masses and mesonic decay constants that correspond to the situation studied on
the lattice. Comparing the energy level spectrum and $SU(3)$ flavor
decompositions of the individual states, it is found that the lowest two states
extracted from lattice QCD can be identified with one of the two
$\Lambda(1405)$-poles and the $\Lambda(1670)$ resonance. The quark mass
dependences of these two lattice QCD levels are in good agreement with their
effective theory counterparts. However, as current lattice QCD studies still
rely on three-quark operators to generate the physical states, clear signals
corresponding to the meson-baryon scattering states, that appear in the finite
volume effective theory calculation, are not yet seen.
