Description
We present results of meson and baryon spectroscopy using the Chirally
Improved Dirac operator on lattices of size $163 \times 32$ with two
mass-degenerate light sea quarks and two+one valence quarks.
Several configuration ensembles with pion masses ranging from $300$ to
$550$ MeV and lattice spacings close to $0.15\,$ fm are investigated.
The analysis of the states is done with the variational method, allowing
for determination of ground states and excitations in several channels.
We discuss the possible signal of scattering states in various channels,
considering masses and eigenvectors.
